I'm posting about the closing of https://movies.stackexchange.com/questions/19686/which-movie-kills-the-most-nazis on the main site.
Part of the justification was that the question is 'trivia' - but it seems entirely unlike the easily-answered-by-IMDB questions cited in Should movie trivia questions be closed? - it's definitely taking research to solve as there's no canonical source (some movie death toll sites contribute, but they focus on big hits and also don't differentiate/rank by the Nazi death criterion). It also seems, frankly, like a less trivial question than about half of those on the main page right now that ask "what movie was a talking donkey in" or "what movie was a one-armed kung fu guy in." This is identical in nature to this question as best as I can tell - all are looking for one specific movie that meets the stated criteria. So that seems like a dodge and the justification for closing (mentioned more prominently in the comments on the question, as well) is really the latter two issues cited in comments.
Part of the justification seems to be "ick, violence in a movie, who could be interested in that. Enjoyment? Of killing in war movies? How declasse." Unless this is really Froofy Indie Cinema Stack Exchange, a lot of movies are made to appeal to those who want sex, violence, action, or other exploitation cinema. Unless I missed something, these haven't been put off topic. Whether people are just posing as Internet-PC-police or what, I'm not sure, but it's pretty obvious that's a major part of cinema and why there's a dozen war movies playing on the TV right this moment. This isn't a legit close reason.
Part of the justification is that "this might offend..." The commenters aren't clear. Nazis? Germans? (All the Germans I have ever known would never stick up for the Nazis). First of all, if discussing any movie in which any group gets killed/etc is out of bounds then this SE is in trouble. Second of all - Nazis, for God's sake. Except for a couple old gaffers who are unlikely to be Internetting it up, all the real Nazis are dead and we just have some variant neo-kinds in the countries that don't outlaw hate groups up front. Is the alien lobby going to complain over us talking about aliens getting killed in science fiction movies? And plus - they were evil a-holes. The reason that movies and video games let you kill zombies, demons, and Nazis is that those are, in popular culture, the holy trinity of things you can kill and not feel too bad about it. (Robots and aliens rank in there too, but actually robots and aliens are usually portrayed as more sympathetic that those three in practice.) Is asking a question about war movies killing Nazis really off topic because "Nazis might get offended?" That's somewhat on the preposterous side, isn't it?
