I love how you conflate generally diseffected young men with homicidal psychopaths. That's textbook dehumanization. However, to your point, that is why incels get more attention.

We assume that they are all monsters and thus undeserving of sympathy. It's become a horror story: like witches, satan worshippers.

"See that young man down that street that still lives with his mom? I betcha he's one of them incels. I don't want his kind near my kids. My husband says he's gonna get some of his boys together and give that boy a talking to. He needs to move out!" That’s what dehumanization does. Poor kid might be autistic.

Femcels are voluntary and the term is derivative. Regardless, I will not minimize their suffering. Loneliness and feeling unwanted sucks regardless of your gender. I have sympathy for lonely men and women.
