I am ok with you being gay (I just don't like LGBT because LGBT is overkill, I beleive there are two genders, Male (XY) and Female (XX))
Sex change as child, I dont like that, or at least up to the parents too (you the parent should have a say, hince you are the parent)(cause maybe the parents could tell the child that it isn't a good idea), but I think it should be 18+
