I have spent time on incel forums too, and I disagree with this assessment. There were lots of instances of guys who "got out" of inceldom, found partners and entered successful relationships.

They would come to the forum and share their success stories and advice (and in most cases it was the common sense generic advice you would expect) and in every case the poster would be ridiculed in one of two ways. Either they were never an incel to begin with, just a Chad who had a prolonged dry spell and who had been an imposter or interlocutor (regardless of their tenure on the forum, often of several years) or they were just a flat out liar and imposter who had just come to give the same trite, cookie-cutter advice that they hear from every Chad and Stacey every day.

The success stories only reinforced their toxic ideology.
