That's not what that word means. “patriarchs” aren't men in general, that's why it's possible (and in fast true) that the patriarchy harms people of all genders.

As this post demonstrate, men don't benefit from it, e.g. it makes us live shorter, it encourages suppressing our emotion, it encourages our aggression. Because some (mostly) men in power benefit if we don't unionize, let ourselves be pressed into shit jobs or the military, and so on.
