Incel son.

To fix a incel, is rather easy. He wants to be successful with women, but he does not know how and/or do not have the resources. If you give them the knowledge, looks, money and power, he will have a easier time. If his father is helping, and teaching all the way, it is way easier. I doubt I will have a incel son because I know the way to make him to succeed and I am interested in him being successful. Also, most males of my family have little to zero shame or standards, so even the lowest of women are enough for most of us.

On the other hand. There is no way to fix a slutty daughter. She has the knowledge, and has the resources and is using them. The problem is they are using it too much and putting themselves at risk. She will not hear me, because there is nothing to win (in the short-run) for her. Nor there is nothing I can give her to lessen her behavior. I can only watch and help when she finally runs out of luck. There is nothing you can do here.
