Simp-shaming has always been a thing.
I really don't understand your concern with it though, or why you care so much.
If a guy wants to be a simp, let him. It's just less competition, and higher probability of you getting laid.
You can't force an incel (or any man for that matter) to learn this PUA stuff unless they are truly ready. I'm all for helping the next guy if he needs dating advice, but trying to force the manosphere down everyone man's throat is not the way, and it will never work. These men need to learn the hard way. Just live your life, date women, and enjoy yourself. Stop caring so much about what the guy next to you is doing or thinks. It has nothing to do with your own development.
