Of the 3 transgenders in 1000 people, I think the vast majority are just cross-dressers.  A smaller percentage start on hormone replacement and a tiny percentage actually have surgery.  Of those that do pursue the physical changes, the further they pursue it the higher the suicide rate is.  Attempting to transform one's gender does not seem like a very healthy thing to do.  It certainly is not a healthy thing for society to allow this particular tail to wag the whole dog.
