I think it'd be hard to be an incel and not have gone out and tried. These aren't people that live in their basements and are never exposed to the sun, these are people that did try to go out and get dates. The trouble becomes when frustration mounts and they start taking lack of interest (of 'the right women') as insults which are stockpiled by these people into anger, distrust, hate, turn into loathing hate of the female species.
My objection was strictly technical.
I understand what it's like to go without sex, having gone without since 2005.
The difference between someone like me and others is that I'm not angry about not having sex for 13 years because I haven't really tried. Sex has never been on my list of priorities.
I can understand how constant rejection might twist someone up, but that's no excuse for hatred or violence against anyone.
