I've asked female friends, now I would like a male perspective

It's a tough battle for me. Those who I've talked with probably see a pattern in my post and comment history, but I digress

How should we challenge or combat this notion? I see many misandrists seemingly advocating for female supremacy, with males possibly going extinct and the world becoming safer, more peaceful, more prosperous, etc. The best argument I see people have is usually deontological, that they just want men to stay because they like men. There's nothing wrong with that, but what about from a utilitarian sense? Do men collectively offer something extremely beneficial that women do not? And are men just more likely to be pieces of shit?

And how do you combat the group guilt and shame? Therapy hasn't helped any with this, and I despise the notion of "well you're not raping and pillaging so you're automatically in the 1%", or the idea that male behavior inherently needs to be corrected to society, that males are inherently the problem

I've seen people suggest things from having male rights revoked, castration from birth, males being eradicated, and more I'm probably forgetting. How can we show that the world needs both men and women?
