Personally, I don't have a problem with TS, TG, TV, or otherwise rare subcultures.  Live and let live.

With regards to biblical reasoning, I don't see how any government can legislate morality, and therefore true obedience.  A government's laws can't legislate "faith" or being "born again". 

So as long as TS, TG, and TV types aren't harming anyone, especially children, there's better ways to invest judicial and legislative branch resources rather than through anti-TG legislation.
