How do you think Permavirgins should cope with it?
Ignoring the incels who are looking purely for romantic attachment. Because I don't think you can solve that, that's a very depressing and dark place to be all alone.
For the coomer incels who are just horny? What should they do? Obviously porn addiction is very destructive and bad, but how else are they supposed to get all those urges out? You could say prostitution but, let's be real here, a lot of these dudes are broke as fuck, have no social skills to navigate getting a prostitute? So realistically it's a hole for a lot of dudes that has no easy exit, without YEARS of progress and help.
Many of them have no help or support either, no mental care, no family members that are aware of what is going on inside of them. So they turn to the internet and get involved in these Incel communities because it's a form of cold comfort. They have nobody else. It becomes an echo chamber where all they hear is those ideas over and over. This can be especially destructive for people with Autism.
