..just an example that not every birth is "perfect" in ways you can see.......so too, with genes, 'epi-genes', hormones, etc...they can be different from the 'norm' in ways you CAN'T SEE...it isn't just a case of someone being a bit 'confused' and is in need of some good counseling only.
The people who are beset with a panoply of, shall I say, "Off-Normal" conditions need OUR, as well as specialists', help...let's not mindlessly bully and persecute them...they have one life to live...don't make it any more difficult.
