what im boiling down to is I don't want to fall for someone (say its a close friend) who looks and acts 200% like a girl but is actually a guy. and yes i would know hes actually a guy, but my minds telling me hes a cute girl because that's how i imaged a girl throughout my whole life (hence the traffic light switch).
If that happens with you, then it means you're attracted to transgendered people. You aren't suddenly no longer attracted to transgendered people just because there's none around you anymore. If that creates a dilemma for you, that's an internal conflict.
You don't need to be a girl to like girl things and you don't have to be a guy to like guy things so the whole gender thing is stupid. Changing your gender does not change your love so you can call yourself a girl if you're a dude but you are still a he and must use men's facilities, as a minority your comfort is less important than the majority.
I just want to point out that there's been plenty of times where societies have sacrificed advantages for the majority in order to improve the lives of the minority. The Civil Rights Act, the 13th amendment, and the 19th amendment come to mind.
