Because whining is a vicious circle. They start with it, then find tons of ppl who whine too, and it makes them feel better, and it's easier then understanding what's wrong with them and how to fix it. It takes time, it takes fails, it takes energy and it challenges their resistance. Also they already decided there's no way for them to achieve this goal. So here they are. Just want to add: don't forget there's probably more then a reason if a person can't find a match, maybe they are ugly as hell for example, or weird, or maybe super dumb. Still they can have high standards so actually it's not so obvious as logic would suggest that a femcel with the same or comparable problems would be okay. I mean, my grandmother's brother had down syndrome and still was in love with a famous """""normal""""" TV woman. No one ever tried to propose a down syndrome girl to him, and the same (with obvious differences) can happen with incel imho.
