This is an area that I really need to know more about, so I am searching for information. Australia seems to be the only country where deeper research is being done, so maybe we should listen to them.  The number of trans gendered adults who changed their sex in Australia, and wished they had not, is a very high percentage. There is a gay actor in Britain who says he is so glad he waited until he was older and feels that the sex of the child at birth ,should be encouraged and the one assigned, until children are at least 18 when they can then make those major decisions themselves. I forget this man's name but a prominent star. Caving into this cross dressing phenomena does not seem right to me with elementary school children. Many will regret this. Allowing anyone under nineteen to have doctors interfere with their genitalia should be discouraged as well. This is a complex topic. What is causing all these chromosome problems?
