The cause doesn't really matter to men experiencing these issues, as there's no path to a solution through that. At least not one that is personally attainable.

The men who want a solution to these problems want a solution that is theoretically attainable by their own efforts, rather than requiring something like a complete overhaul of the existing societal structures.

"Cool, we found the source. Now what's happening about that which will help me in my lifetime? What can I do against the patriarchy beside not perpetuate it myself, while my prospective partners are still living in a society controlled by it?"

You can't tell a lady her expectations are unfair because of the patriarchy and use that to get a girlfriend.

A lot of men see posts like yours and feel like they're being told that you think the problem's solved because you found the source. And some of them feel like just tossing it on the abstraction of "patriarchy" is an excuse to try and blame the problems they encounter on themselves. "We wouldn't hit you if you behaved right!" or "You men made this bed, now get fucked in it" sort of shit.

Or it just means that they have to become part of those powerful men, part of that patriarchy, in order for things to work out in their favor. Because it's too big for them to somehow slay and then reap the benefits of a patriarchy-less society. That's where some parts of the "alpha" bullshit comes from.

I get that's not what you're trying to do, but it's worth saying. I'm happily married for almost a decade now, but I spent far more time than is healthy on 4chan growing up, so I'm somewhat familiar with the mindset, and I've seen plenty of men heading down this path express these sorts of feelings when they see comments like yours.
