You seem to know this subject better than I do, so I believe you. I've been in a happy relationship for almost 20 years. So this entire phenomenon couldn't be further removed from my reality..
Basically incels are a specific thing, involuntarily celibate, but also what really defines them as incels is their misogyny stemming from a belief that women are to blame for their being celibate and not the fact that they themselves are the issue.
So like I've been celibate for about 4 years now, but I know I'm human trash not women, so I don't believe I'm considered an incel.
Don't sell yourself short! I don't know you, you could be a racoon for all I know, but most people are at least a little trash, which means you're probably just as good as most people. Better, even, based on your willingness to consider your own responsibility for your life.
