What's a person supposed to do, when they are confronted with a person, roleplaying as the opposite sex, living in the uncanny valley, such that everyone that sees them has the same reaction - That chick's a dude! The visceral reaction that a person has upon seeing that is not hateful discrimination, it's the same as seeing a leper - "oh, that's a weird look, keep your distance."
It can't be hate if it's a biological reflex.
