No one who has thought deeply about the principle really believes in it. Equality™ is just a ruse, a con, pulled out of the hat to gain advantages and then quickly put away lest already existing ones be lost
Wimbledon Tennis: Feminists Preach Equality While Enjoying Inequality
Could you imagine lightweight boxers complaining they don't get the money and exposure of the heavyweights, calling the different treatment "staturism"?
This is essentially the situation at the Wimbledon tennis championships this week, with, for example, Hannah Wilks at the Guardianwriting, "A new analysis of matches scheduled on Centre and No 1 courts shows that Wimbledon organisers routinely favour male tennis players over their female peers." She calls this "sexism" and "sex discrimination."
Actually, it's called marketing.
