The folks who aren't sexually confused just go on acting normal and treating people normally and get castigated for not being telepathic.
How am I supposed to know whether someone is a butch hetero, butch lesbian, transgender before transition, transgender after transition, a garden variety cross dresser or whatever the flavor of the day is?
What I do know is that the number of true folks who truly are of indeterminate sex is minuscule compared to the "gender" confused, tabula rasa self identifiers.
