The bat cycle.

Feminism creates girl bosses who 'need a man like a fish needs a bicycle'
This leaves some men desperate enough for a bat pony to move in and breed
Bat fillies are born and raised in human society (instead of the woods)
Young human girls get hissed at by bats when trying to talk to boys at a young age. By highschool, older bat fillies constantly make fun of them for showing interest in boys or straight dating... and guys tend to side with the bat who was their childhood best friend.
Many young women grow up traumatized around guys. Feminism and society assures them that men are the problem.
More women become childfree girl bosses, allowing more bat ponies to give birth instead.
The next generation has even more bat fillies in it.

repeat until...
