I joked about mocking the incels for not getting laid, but on a serious note - a lot of these people proclaiming themselves to be incels, whether publicly or not, probably need at least some pushback from somebody, because there is a shitload of overlap between the incels, Qanon/conspiracy types, etc.
As mentioned earlier, they are going down Internet rabbit holes where nobody is challenging them. 25 years ago, if these people were spouting off insane bullshit about conspiracy theories that they were a victim of or whatever, a parent or sibling or other relative or friend or classmate would usually set them straight, or at the very least, they'd see the people around them not following the stupid bullshit they are pushing. And truthfully, some of that pushback would be basically bullying, as in "you're a fucking idiot for believing that, just lower your standards and go get laid you moron".
Way too many of these incels, as well as school shooters, etc., all seem to have a problem of being enabled by those around them when it comes to stupid shit. Maybe it's a parent who is too tired from work (or is ill-equipped) to monitor their internet habits or spend time with them and know what's going on with their lives, or they don't have a lot of people in their home lives who can either provide a role model for them, or at least keep them from buying into the shit like Andrew Tate, etc. are selling.
