If you're transgendered then you ain't the real thing, and that's all that matters. Having a preference for real women over trannies might be a hangup, but it's a mere anthill compared to the mental problems you have if you feel compelled to become a trannie in the first place. So if it's not kosher to criticize the serious mental health problems of trannies, then it's absolutely impermissible to question the much smaller issues of folks who have a preference for real women.
