I myself once learned 380 digits of π, when I was a crazy high-school kid. My never-attained ambition was to reach the spot, 762 digits out in the decimal expansion, where it goes "999999", so that I could recite it out loud, come to those six 9s, and then impishly say, "and so on!"
"If you're attracted to a pretty girl with long, straight, brown hair and a strong, self-possessed personality, just walk away, it's almost certainly going to get you killed."
Loudly and intrusively hating things that other people like.
If someone likes a terrible show or movie or musician or whatever else... just let them like their thing. It's okay to state your point if you somehow get dragged into a conversation on the merits of a given thing, but making a point of shitting on something that someone likes when they're in no way harming you is just shitty behavior, and it's not going to accomplish anything.
IIRC, there was a study done with cats hearing recordings of random voices saying random words, random voices saying the cats' names, owners' voices saying random words, and owners' voices saying the cats' names, and then carefully measuring the cats' responses.
The findings pretty convincingly showed that cats full well know their own names but choose to ignore the calls.
There was a great interview with a woman who had written a book on the Manosphere and she said that it's "funnel-shaped," which is to say that the first stages are nowhere near as extreme as the ones they lead to. It starts off by talking to lonely young men and telling them that their feelings are valid and that they have value, both of which are things that young men very much do need to hear! But the pipeline then moves them from that to "Your feelings of isolation aren't your fault" to "Your negative feelings are women's fault," and then you're off the primrose path to "Women aren't people" and "Women deserve any horrible treatment you can think of."
But the earliest stages are ones of finding young men that aren't having their emotional or structural needs met, and filling that vacuum in.
