Involuntarily celibate people are that way specifically because their personality is shit. Most of them are narcissistic for sure, so they turn off any self respecting woman.

Now, there will always be women with absolutely garbage self esteem who will enter into a relationship with such a person because they feel like they have no other option.

But yeah, you’re right. Being an incel is more about their personality disorder than not having sex. They basically want a house/sex slave and don’t see women as people.
