That's not what the Southern Poverty Law Center says.
"Several key influential figures use mainstream platforms to promote their hateful message and recruit and radicalize others. The main subideologies of male supremacy include incels, Men Going Their Own Way (MGTOW), pickup artists and so-called men’s rights activists."
Everything we have seen so far from the rhetoric of incels, PUAs, and MRAs suggests that the primary goal of these reactionary groups, like much of the alt-right and other online supremacist groups, is to regress to an idealized state of white, heteronormative male control and power. They want to see women subjugated as vassals, objects to be used primarily for men’s sexual pleasure and reproduction: pliant, obedient, and servile. The end — achieving this extreme, patriarchal utopia — is considered infinitely more important than the means, which may include everything from trickery to harassment to assault to mass violence.

And that's what most experts who have studied the manosphere also say. There is a HUGE overlap between so called Men's Rights and violent misogyny, but also homophobia and racism. The manosphere is made up almost exclusively of middle class white men who are pissed off that their unearned place in society is eroding, not just by women, but by Jews, Black folks, gays, etc.
The manosphere is well documented to be recruiting young men into violent hate groups that dehumanize women, and advocate for things like legalizing rape. The Nazi guy is also a violent misogynist. That doesn't mean all men in the manosphere are Nazis, but anti-Jewish hate in particular is rampant. Many men consider feminism to be a Jewish invention. Other types of casual racism are also common.
A compliment is a show of respect - not a drooling manifestation of how you view someone as an object of desire. If you don't understand the difference, and how and when it is appropriate to remark on the physical appearance of someone else, you are a part of the problem.
And please show me the career of even one famous man who has been "destroyed" by any woman. In truth, the reverse is true -it often takes 10 or 20 or 60 complaints and accusations before anything is actually done. I'm actually working on a new story about that and how in the UK a man is 230 times more likely to be raped than he is to be falsely accused. So yeah, that's not an actual major issue. It does happen from time to time, but not very often - whereas sexual violence against women happens incessantly, mostly with no repercussions. According to RAINN, every 68 seconds an American is sexually assaulted - most of them women.
