I'm not gonna jump in on that thread about 'all men' but I am gonna say this:

While it's true that not all men do X, it is absolutely more true that patriarchy socializes ALL MEN to accept or be blind to certain truths about their position, importance, and relevance in the world.

Almost everything all men think of as 'natural' about their status in the world is not, in fact, true.
It was crafted through oppression, suppression, and violence.

It is also true that it takes an enormous amount of deliberate de-conditioning to throw off patriarchal thinking and praxis.

Those for whom 'not all men' truly apply (which is a small enough number to be sad and pitiful) know this to be true.

And so do the rest of us.
