As someone who formerly suffered from that problem I think a big part of the issue is that the world is incredibly isolating and alienating, so you get stuck in your head and can't just talk to people normally. We need to stop creating suburbs that act like prisons for developing minds. We need more third places. And we need to find some way of teaching people to have healthy relationship-building interactions with other people without making anyone feel unsafe.
Travel helps a lot. Gives perspective. Also there's a whole ass planet of people that will boink you out there. No need to geographically lock your romantic life. Just ya know, don't go to brothels and shit, that's no bueno.
Brothels are fine. Treat the workers with respect like you would anywhere else and maybe it will teach former incels to unironically not put the pussy on a pedestal.
Yeah I got no issues with sex workers, and maybe it would work for incels, it's just not my thing. I was more specifically saying I'm not advocating for sex tourism. Just go have a good time, eventually someone will want to see you naked.
