Didn't we learn as children that stereotypes are bad and hurtful? Like why is this one an acceptable thing to lump all men together under the same group? The rhetoric rarely makes a distinction. It lazily doors not differentiate the different problem groups within that and stops at blanket statements that cover more people who aren't the issues than are.
When you treat an entire gender as the enemy, stop being surprised when the young men are increasingly not acting like allies.
