I don’t know what you mean by “solving the incel problem” exactly, because no one is entitled to sex, nor should they be. But sexually frustrated young men are a social problem. They commit crimes up to and including rape and murder at a higher rate.
I *do* think everyone is entitled to equal treatment under the law and by law enforcement and that is what these protests are about.
The best advice on a personal level I can think to give incels can be found at the top page of this stream right now
