Both men and women want to date women.
A man has neither breasts nor a waist — how could anyone fall in love with a square?
Incels and men with low testosterone, aware of their vulnerability to the primal attractiveness of women, instead of worshipping her to get a little attention, avoid any close interaction with them. And sometimes form romantic relationships with other men and begin to imitate feminine behavior themselves in an attempt to gain the power they naturally lack and fear — resulting in a caricature-like narcissism (Patrick Bateman, drag queens, etc.).
In order to make women at least somewhat interested in men, the patriarchy took away their access to money, so women had to pretend interest in men’s personalities just to buy bread.
Some men can forgive their woman’s infidelity with another woman, understanding how difficult it is to resist their overwhelming charm. But if she cheated on him with a man — then she is dirty, because sleeping with a square is only acceptable for obtaining resources or, if her maternal instinct has awakened, for fertilization. And since a man’s main strength lies in resources (in the past — mammoths, today — money) and strong genes with healthy sperm, this tells him that he has failed natural selection.
Humans are aesthetic beings. In romantic relationships, the key factor is sexual attractiveness. How could a person with a developed sense of beauty and a healthy mind choose SpongeBob over Adriana Lima — unless they themselves are in square pants?
