If the person Mandalay was responding to is a rightist (and I think it's pretty clear he is), then it is a true statement that the person being addressed is part of a group that commits political violence.

But saying, leftists perpetrate attacks all the time as fc did doesn't break the rules?
Theres no agree or disagree about it. I Simply do not understand the principle behind this application of the rules. It seems incoherent to me.

Given the who he was responding to, obviously "you guys" is referring to a general category of right wingers

Why arent my posts showing up in real time? It appears a mod has to approve each post of mine? Why is that?

Just appalling.
Fc writes the following and this is the guy you mod?
"They whipped themselves into a frenzy over Trump, and now someone has actually tried to kill him, and for many on the left there is no actual way to walk it back, nor ability to recognize the realities of their position. All they know how to do is double-down, which makes further incidents inevitable, which in turn makes reciprocity from the Reds inevitable."

Who are you referring to? The guy who "stars" in that video is an older man with a goatee and is definitely not our shooter.

Why should I think that the second risk is greater than the first? Your post says that it is so, but provides no argument why that is the case.
The sunlight has the potential to heat the ground to over 100ºC (212ºF). The reason it doesn't get that hot is because the ground conducts heat to the air, which then convects upwards. So the sunlight, during the day, has the power to heat the surface far above the blackbody average.
This is a misunderstanding. Blackbody temperatures are often reported as global averages, which is why the moon daytime high is above the "blackbody temperature" -- because the average blackbody temperature includes the night side. You can do the Stefan boltzmann calculation for the day side of the moon. You will find that the daytime blackbody temperature is about 400k, which is very close to the measured daytime surface temperatures.
and the 'average' temperature is overall higher than without.
This is the part that you still have not shown. I would appreciate it if you would do just the thermodynamics 101 energy balance calculation to show the effect.
A packet of air on the surface on the day side will perhaps pick up energy from the surface. This warms the air, but also cools the surface. If this packet of energy is moved to the night side, it will deposit it's energy onto the surface; the surface will warm and the packet will cool. This tends to equalize temperatures between day and night sides but cannot provide a net increase in temperature (of sum of day and night side) due to conservation of energy. The global average temperature is still blackbody (day side being warmer than global average blackbody and the night side being colder).
getting as cold as they do without an atmosphere (-100ºC on the moon), much like how a blanket works.
No, the blanket analogy is invalid. If the gas is transparent to radiation, then it provides no barrier to radiative heat transport from the surface. In fact, the presence of a gas would reduce the insulating effects because it provides a conductive/convective path away from the surface (vacuum being the best insulator).

I would add that the skin tone "randomized palette" seems like a pretty clear CW angle as well.
I'm not seeing it. Can you explain what you mean?

Gotta be honest this seems like a very mild culture war angle. The models were already quite androgenous and subdued in their sexual characteristics (certainly there was no option to look like Schwarzenegger or Parton). The one clear CW aspect is the removal of distinct genders... But c'mon. Have you met the Pokemon go community?
The pictures of the new models linked look just look like garden variety incompetence. Yes the waists are wider but there's also just a general reduction in detail and quality. Looks like someone decided to cut corners, maybe chose the cheap 3d modelling house.

I think the nonsequitor is the assumption that whatever dynamic is happening in a green house must be the same dynamic that is happening on a planetary scale atmosphere. Its possible that one effect dominates over another in different contexts, or is just not applicable.
Maybe, why we should think they would not be the same: the "hot house effect" relies on a comparison between temperatures inside vs outside, where outside, convection tends to draw away heat. But on a planetary scale, "outside the greenhouse" is mostly just the vacuum of space where convection doesn't occur.
As far as I can see, you still have not given any explanation for how the lapse rate effect can result in temperatures far in excess of blackbody (day/night temps being irrelevant since we are interested in average temperatures)
Take a packet of gas that starts at the surface, rises to its maximum height, and then falls back to the surface. Initially it will be in equilibrium with the surface temperature. If the gas does not absorb or emit significant radiation, then it will have the same temperature at the end of the round trip as the start. There is still no mechanism by which the gas packet temperature would exceed the surface temperature nor by which surface temperature would exceed blackbody.
And obviously an entire column of surface plus air above it, is what will as a whole be radiating to space.
If a packet of gas does not exchange (absorb or emit) significant energy via radiation then the "whole column of air" will not transfer energy to space.

I'm going to add "too stupid to be allowed to vote" to my list of mod-approved ways to characterize people I disagree with.

The question then is: as the adiabatic lapse rate explains the grand canyon temperature difference, why would it not also explain the temperature difference between the surface and the effective blackbody temperature?
No, sorry, a rhetorical question is not an argument. For the second time, you are still doing the thing you accuse your opponents of: positing that some effect is explained fully by your own pet model without providing any independent evidence that it does so.
It must be noted the effective temperature of Earth (255K, -18C) is indicative of the average amount radiated by an entire column of surface plus atmosphere above.
Are you or are you not trying to rule out that radiative heat transport is a significant factor in atmospheric temperature?
If you neglect radiative heat transport then atmosphere temperature can only ever be less than surface temperature, which is blackbody.
On the other hand, if you include radiative heat transport, then you must acknowledge that different gasses have different absorption/emission spectra and so their behavior cannot necessarily be compared on 1-1 ( or equal density) basis.

I dont see how those are relevant to the study I posted. Those were open systems where mass exchange with the environment is possible, but in the one I posted the gasses are sealed in balloons.

Here is a benchtop experiment. Figure 6 apparently shows that variations in the density of air in a balloon do not affect it's cooling rate, whereas it does for a CO2 filled balloon. This would seem to contradict your claim that it's a spurious density effect.

After admonishing me for comparing model predicted temperatures of Venus to observation, you link me to a video where the adiabatic lapse model is compared to observations, asserts without independent evidence that this fully explains venus' surface temperatures, and what's more tries to generalize this to earth. This is unsound logic by your own argument.
In any case, I would appreciate it if you would explain your position to me in text, here, rather than sending me links. Or at least provide additional commentary along with the link. After watching that video I am no closer to understanding how adiabadic lapse rate results in surface temperatures in excess of blackbody nor why I should favor this over the greenhouse effect.

Your linked post mentions nothing about adiabatic lapse rate nor how it can explain Venus' temperature being much higher than would be predicted from blackbody equilibrium. Care to explain in detail what you mean?

From your first Twitter link, the guy gets it wrong right off the bat. "How can the GHGE work after so long a night?" Because of the thermal mass of the ground and atmosphere, and the insulating properties of the atmosphere which is much thicker than Earth's, and because high winds on Venus tend to equalize day/night side temps.
This guy doesn't know what he's talking about.
This is just a gross failure of imagination. Would you trade places with any contemporary non westerner, or any premodern?
The worst things you can say about the modern West is that 1. we are so fabulously rich that basic living necessities are essentially free and so we plow all of our surplus into zero sum positional goods. 2. We demand such a high quality of life that we continually push our institutions to eliminate the n-th signma risk of living past the point of diminishing returns.
About half the word is either white or East Asian. There is plenty of "high quality" genetic stock of that's what you care about.
This genetic stock wasn't present at the start of the universe. It was created out of nothing by selection effects. Equivalently high quality genetic pools can be created if they are adaptive
