Not a familiar term, but I looked it up, and I gather these are community activist types?
Fare how, living together or fighting to the death?
I'll go with living\working together.
They seem pretty different, but barring other changes, I don't think the sort of socially awkward type incel I have some familiarity with would participate.
That's the problem in a nutshell. For whatever reason, they can't participate normally in social settings, and it eventually leads to resentment, seeing themselves as victims of unfair women, seeking like-minded people for social interaction, and sometimes violence.
I'd also guess if they could overcome that, a group like the colectivos could reverse a lot of that damage, and ultimately "cure" the behavior, in many cases.
But then if that was easily overcome, this wouldn't be much of a problem. There's nothing stopping them from engaging with similar groups at home.
