I think you’re confusing ‘patriarchy’ with men in-general.

Of course it’s not men’s fault that society is failing them, but that doesn’t mean patriarchy isn’t a part of the systemic problem.

A big part of the suffering of working class men is inescapably about our material conditions, and the way in which society reinforces those conditions through gender roles. We can both have sympathy for those disenfranchised men and recognize the problem and where it lies.
