Certainly we should not withhold compassion from people with gender dysphoria, and I said as much!
But biology is complex, and society is complex, and therefore I wonder whether the current situation, which is sculpted by extreme historical prejudice which is dissipating somewhat, will continue to be true.
This has, for instance, been the pattern with sexual orientation as far as I can tell--as the stigma of homosexual actions has been removed, the number of people identifying as bisexual has increased dramatically (far more than the number of people identifying as or identifiable as homosexual).
