It's really simple: Assume all or most men are predatory and abusive.
When you look at the way that men are talked about online by women, the way everything a man does is treated with suspicion, the double standards that seem arbitrary--it all snaps into perfect focus when you understand what the fundamental assumption the person speaking on us is working with.
Just like GPS doesn't work if you don't understand the fundamental physical principles of gravity, mass, and time dilation, modern misandry seems confusing until you realize the fundamental principles the people spouting it are working with: men are predatory, psychopatic, and aggressive about everything.
And in modern online communities, you can find yourself in an echo chamber where people who already agree with your assumptions just parrot them back to you in different ways. These women don't want men to be happy under any circumstances and engineer scenarios in which no matter what, he's a bad person.
Struggling to get dates domestically? he has a bad personality
Every woman that has met him actually says he's a great guy? well he's just not trying hard enough.
His own friends and family can't figure out why he's single even though he's doing everything they told him to do? well his standards are too high and he's unrealistic.
He shows screenshots of him getting turned down by women who look like big moochie grape? well...he's not owed attention or a relationship from women.
He travels to another city or country and finds women there that treat him with kindness? he's probably paying for it
He shows evidence he's not paying for it? well she probably doesn't know better. She's maybe a child and too young to see he's a predator.
No matter what a man says or does, when your mind is made up to believe that most men are terrible and social media and conventional media at large have re-enforced that belief, you can justify anything awful you want to say or do to men.
No hate, y'all just bragging about exploiting people in foreign lands. If y'all didn't make a culture out of it, then nobody would say anything.
