How in the world is it a problem? Saying we shouldn’t judge an entire gender just for some people being assholes is the same as saying it about race, or any other broad category like that.

Problem with that argument, is that it's more like an oppressed group discussing what's oppressing them & told they can't. I don't like when race automatically gets dragged into arguments, just because, but since you did, I'll stick with that. Men making the #notallmen complaints, is no different than when #notallwhites being shouting over black lives matters.

When groups are discussed in this manner, it's as a class... not an individual.
