If women want to call all men as potential rapist because of 1% men who commit heinous crimes. Then why are men expected to #believeallwomen when more than 1% women falsely accuse men.

I don't understand why generalization of men are expected, but generalization of women is not.

Women can assume all men as potential rapist, but men cannot assume all women as potential false accusers.

Can someone explain why is that? How fair is that?
