Men who hate women in generally will usually keep it to themselves in public for the most part. They’re not going to go on a tirade about how much they hate women to someone they don’t think is going to disagree with them, which might explain why you’ve not seen it personally.

Exactly this. Misogynists don’t talk about that shit with men who they don’t already know share the same views. They are universally fragile and insecure. They don’t want their beliefs challenged especially not by another guy. The way it works is, if they don’t know you they will say something that teeters on the edge of misogyny without being egregious enough that they will get called out for it. If you entertain whatever they say then they’ll start going mask off around you because they know you’re “safe”. If they get rebuffed then they keep the mask on around you.

I’ve known a couple of guys where various women have said that they were sexist creeps but I never got that from them. But in hindsight for both of those guys I remember an interaction where they would say something about a woman or women in general which just verged on inapropriate withough going into “dude wtf” territory. Both times I essentially just gave them a weird look and they never got near that line with me again.

This is why most guys don’t see misogyny nearly as often as women do. When a misogynist “tests the waters” with another guy they do it in a way that is subtle enough to seem entirely innocuous in the moment.
