At the root of the distaste for incels is discomfort with acknowledging the true nature of female sexuality

Basically, women want good sex with pretty men, just like men desire young femoids. Male beauty is an object of sexual selection which females desire at the primal, cellular level. However, they are also able to prostitute themselves to men for resources in wink-wink arrangements involving some emotional support but at the root of which is male material provisioning. Incels hit a nerve for bringing this unmentionable reality to the forefront of the mind in the women prostituting themselves to men they don't truly desire and in the men having to be simping, provisioning monkeys in order to get star-fish sex once a month with toilets likely to be reminiscing about the Tyrones and Chads who more welcomely mounted their younger, hotter, and tighter selves.
