Home run by Richard Klagsbrun:
We shouldn’t discriminate against transexuals in any way.
They are people who have a condition that causes them great difficulty, and it is often a troubling and courageous effort that leads them to alter the sexual identity with which they were born.
But consider that their condition is something that requires surgery to correct, which is covered by publicly-funded heath insurance.
So it is, by definition, an illness.
