After Columbine, with reports (true or not) that the killers had been bullied, nobody took that to mean that the anti-bullying crowd is dangerous or that people who claim to be victims of bullies are really just misanthropic killers. "Geeks who don't like to be bullied are part of a murder culture".
(Well, I'm sure some people took it to mean that, but we recognize that they're being assholes about it.)
But replace "bullied" with "rejected by women" and all of a sudden it means there is rampant misogyny among angry geeks. No, it's not, it means that if a lot of people are rejected by society, a few of them will become killers. This doesn't mean that the complaints about rejection are wrong, or that geeks with such complaints are dangerous, any more than Columbine showed that complaints about bullies are wrong, or that a higher murder rate when unemployment goes up shows that we should ignore unemployment. (What's the unemployment equivalent to rape culture?)
