Regarding your comment about "Manosphere", "Red Pill", etc. on the other thread you locked, I've never been to those sites. I've never read their material. I really know nothing about them except for hearing people mention their names only a few times.
You've denied this before, but you must be a frequent consumer/poster of similar content on other sites. The so-called "Man-o-sphere" is a network of sites on the Internet dedicated to opposing feminism, bringing back true masculinity, teaching men how to live and thrive in today's world, etc.
From what I've seen of such sites, they are A) predominantly non-Catholic, B) they only give lip service to those who are seeking a monogamous relationship ("these techniques can be used to get that life-long partner, if that's what you're after...") but C) most of the men there are worldly/neo-pagan, and are seeking to use, abuse, play with, and throw away women in a sort of bitter, anger-fueled revenge spree. They seek to learn the true psychology of male/female relationships in order to exploit it for their own perverted sexual exploits.
They have some truth (which makes their doctrine attractive) but a LOT of error, and certainly the wrong spirit (bitterness, complete distrust and hatred of women, etc.)
I've visited such sites on occasion -- mostly out of curiosity or when I had lots of free time -- and you sound *exactly* like them. You use all the slang terms (MGTOW, LARP, beta/alpha male, incel, etc.)
I'm sure there's a lot of crossover between such anti-feminist quarters of the Net and white supremacist sites, for example. Why wouldn't a bunch of white supremacists be against feminism and looking out for themselves? In fact, I'd be surprised if they weren't!
