I'm against trooning out that soon.
However, 16yos are able to drive and do other shit. Just like you don't mature overnight, you don't get all responsibilities and rights overnight. People need that to learn to be responsible for their lives and actions.
If she was 18 and retarded enough to think "I don't want tits, take them off" and "I hate being flat :-(" at the same time, she's beyond retarded. No really, what did she think was going to be the result? If she didn't fuck herself there, she would have done so in another way. Besides, so many tranny movements preach about not having to have procedures to be Valid™, so I'm not accepting that excuse. People need to use their brain or pay.
If there was a 5-6yo child who never got burned by fire and instead of touching it with just one hand it jumped into a fireplace, I'd also call that child retarded, even if their parents are legally responsible because of age.
I'm sick of dumb people doing dumb shit because they're dumb and then shifting blame on others. All this required was basic info and reasoning.
