You may be right about their narcissism possibly making them bad parents (I do wonder how much this is a learned trait) but I don’t think these women are femcels.
They could get plenty of guys, they’re not remaining celibate, they’re just holding out for a level of man that maybe they had briefly a few years ago and think they’ll still find today.
It would be better for all of us for them to come back to reality and join the extended order rather than continue down this self-absorbed path but I don’t see it happening. The other women in their circles are reinforcing these attitudes and they’re kind of collectively going down with the Titanic.
