The question Why did America only attack Japan with atomic bombs and spare Germany? , which in more than one version speculates that Jews were responsible for a purported decision that Hiroshima and Nagasaki would be nuked but no German cities, hasn't been deleted. The question is both factually ignorant, in that it's fairly common knowledge that Hiroshima happened after victory in Europe, and offensive, as it's linking an ethnic group that suffered genocide with a large-scale killing, a common tactic of genocide deniers, which is still being used. (In case it needs mentioning, I'm more worried by hate speech than factually incorrect content)
By contrast, when I added comments critical of the question, saying "#JewsDidHiroshima", and later "#JewsDidHiroshima /sarcasm", they were deleted.
I can understand a strict moderation system deciding to delete my comments, or a hands-off moderation system allowing the question. But I'm rather puzzled by a moderation system that allows the question, but doesn't allow my comments.
