If someone wants to give up dating due to their looks, age or genetics (that includes mental state) that’s a totally valid reason if you ask me. As long as it doesn’t translate to misogyny no one will get hurt. However a lot of people seem to be ticked off by this idea, why?
I want to set aside my skepticism that this philosophy can be separated from misogyny.
Even if it could, it hurts the practitioner. This is a philosophy of nihilistic abandon and self-harm. If someone has adopted a radical belief in their own hopelessness and worthlessness, and the associated beliefs that life for them can hold nothing but suffering, that person is in crisis and needs help. There isn’t a healthy version of that, and we should consider those people at great risk and in need of assistance.
It does hurt someone. It hurts the person who is adopting these views.
