This isn't a matter of telling anyone, this is a matter of people in abusive systems realizing it on their own.

Its not random anons asserting the corrupt nature of these relationships but the folks who escaped them.

“those loudest about being victimized are the most eager to take their pound of flesh”

The loudest folks are the social media influencers. You'll regularly hear your Tim Pools and your Jordan Petersons, your James Dobsons and your Elon Musks, rant about how men are victimized by femininity, while profiting off the insecure and insulated men who have been roped into their carny acts.
