I post not infrequently on these issues (this is an aversion for me as this is a case where the female party is unambiguously wrong and behaved in a manner no better and arguably worse than the two guys) and I never see what you claim. So I'm not saying you're wrong, but I am skeptical of it being endemic to the topic.

The post whose downvotes you are ascribing to misogyny can also just be called a poor post. Which, FWIW, I do.
