The main reason ZP failed was actually the affiliation with pedophilia, not inceldom. Yes, I myself think it's hypocritical that any downtrodden group shits on a different group of rejects but it is what it is.
Usually there's this mistaken idea that if you can show some last remnant of virtue, society might be more accepting, even though that does not happen. So they will be like "at least we are against pedos, we aren't THAT bad."
Maybe a pedo forum might do the exact opposite and say, OK we are bad for liking little girls but there is worse, people who *cough* fuck animals *cough* Eww gross, we are at least a bit normal."
BTW,
@Oxblood don't forget that on incel forums it works in the reverse too: I was very controversial on incel boards. Some dudes even wanted my death for being a horse fucker.
Every incel has different copes though. What works for one incel may not work for another incel. I for one, will not trannymaxx, fuck trannies or sexdolls/robots. If that works for you, fine by me but leave me alone with the only cope that works for me: fucking mares.
