I really don't understand why we need to openly discuss politics in the first place on a forum about lewd anime girls. It doesn't really make sense to drop that the latest genocide in "x" was caused by "x" when people were just discussing what anime to watch a few minutes ago.
You might be entitled to whatever you'd like to say, but think about it - there's much better avenues on where to discuss them. I'm all for free speech and uncensored discussion, but I also agree that politics should be kept to a minimum outside their respective channels and subforums. If you think there's not enough people to discuss about it, start recruiting for the channel/group, or look for more dedicated forums for said topics.
Of course, it's inevitable that it might leak into #general or The Lounge every so often, but that doesn't mean we have to outright stop it on the spot, so long as it stays civil and respectful like any other discussion. If people seem uncomfortable on a certain topic, then it's on you to ease up on it.
