A common criticism I hear from BP is "TRPers are just bitter that they've been hurt by women!"

I actually agree, I am pretty sure every mgtow/dark triad/player/etc was once a beta. And at some point they were let down by women, e.g being incel, being cheated on, being broken up with. Myself included. If you do a Q4RP and dudes are honest, I'm sure they will admit it. This has happened to pretty much all manosphere legends (Roissy, Rollo, Roosh)

However, I fail to see how this criticism affects these men's position. If anything, it only validates it. If I state that "pitbulls are dangerous", and you answer "you only say that because you were bitten by one", well, you've just proven my point?

By shaming men for having negative experiences with women, all you're doing is acknowledging that a lot of women really screw the lives of a lot of men, and end up reinforcing their "misogynistic" (more like "defensive") opinions
