This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.
Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.
We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:
-
Shaming.
-
Attempting to 'build consensus' or enforce ideological conformity.
-
Making sweeping generalizations to vilify a group you dislike.
-
Recruiting for a cause.
-
Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.
In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:
-
Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.
-
Be as precise and charitable as you can. Don't paraphrase unflatteringly.
-
Don't imply that someone said something they did not say, even if you think it follows from what they said.
-
Write like everyone is reading and you want them to be included in the discussion.
On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Notes -
I'm not an expert in shop, but what's stopping people from publishing digital, open source schematics for using more traditional metalworking to make firearms? Would it be too effective, a kind of "how to build a nuke in your kitchen" type thing, or are 3d printers really that much more accessible?
What does it take to make an AK, probably more than just a lathe right?
Nothing is stopping them. If you have a metalworking workshop you can make a Sten SMG. Or an AK. The benefit of things like FGC-9 is that you don't have to be seen around a lathe or a clapped-out Bridgeport machining something that looks very much like a gun barrel or a receiver.

I read a decent primer on making zipguns (the name for what you're talking about) a while back. Takes some skill to make a weapon that isn't going to blow your hand off but it's definitely not rocket science. Sufficiently motivated people do it; Shinzo Abe was recently assassinated with a zipgun.
I'd take a zipgun made of metal over a plastic one any day.
These aren't plastic, though. It's a metal gun with plastic frame and some minor parts.

Because the people doing the publishing generally rent apartments or reside in condos without garages. Autistic single nerds in their 20s and 30s don't generally own homes.
It's hard to make schematics when you don't have the tools to test them with; by contrast, even a shoebox apartment can accommodate a 3D printer, a vise block, a bucket for EDM rifling, and some hand tools.

Nothing. It's easily accessable. You can just search "AR lower CNC file" and it should show up as the first result.
Building a gun from entirely from scratch is extremely difficult and costly for one person, but most of these files assume you're only interested in making the part that's actually regulated (the lower reciever).

I’ve assumed that’s already the case. Not sure how amateur gunsmiths are most likely to learn. I guess it wouldn’t be too surprising if (at least in America) it’s one of those skills managed entirely by cultural norms.
