1) Highly immoral, but impossible to restrict.
2) I think it's undeniable that it's a mental illness, because it does cause severe distress. The usual treatment is changing physical gender, but if it were possible to "cure" transgenderism, then I think it should be up to the individual which of the options to take. I feel the same way about sexual orientation: if a treatment to turn a gay person straight were devised (one that actually works unlike the pray away the gay nonsense) then I see no reason why it should nto be widely available (though of course nobody should be forced to take it, and if the reverse exists, that should be equally widely available).
3) I don't really feel qualified to answer this.
4) I agree with you here. It being a choice or not being a choice is immaterial. The fact of the matter is that it is a harmless characteristic that only leads to consensual interaction between adults. It's just a biological question at this point, and perhaps a theological one to some degree, but the latter has no place in lawmaking and the former has no relevance.
