There we go, you both have the inability to understand they they don't have a choice.
With mental issues, you often don't have a choice, it's not like they, as someone said decided to just want to act/be like a girl.
It doesn't work like that, there's a difference between "wanting to be a power ranger" and "having a physcological condition which has gender identity issues".
You don't choose to have it, just like other physcological issues;
Depression, Bi-polar disorder, Paranoid Schizophrenia, OCD, Personality Disorder, PTSD.
You don't DECIDE to have it
Please understand difference and don't hide your insults, to the point you need to change the subject with ridiculous assumptions about a child voting, seriously? That's childish.
I've met someone with GID, I understood it, didn't make a fuss about it, they also had it as a child from 9 years old; but they dressed as their actual gender but acted the opposite.
