I moved the big meta-level comment thread from "Yes Requires the Possibility of No" over to here, since it seemed mostly unrelated to that top-level post. This not being on frontpage also makes it easier for people to just directly discuss the moderation and meta-level norms.
Note: you can generally talk about political stuff on your personal blog section. Part of the point of the frontpage/personal-blog distinction is so that there can be a bit of soft-pressure there without actually preventing people from talking about things.
There are certain areas that we might need to make individual judgement calls about (see Vaniver's comment elsethread). And in general when discussing hot-button political issues I'd suggest you reflect on your goals and life choices (since I think it's an easy domain to think you're discussing something important when you're mostly not). But that's different from a ban.
