If there is a test or a cure I predict it will be in wide use very quickly outside the US. Most of the world is NOT PC.
The populations of China and India find this sort of thing quite useful. To begin with they will start aborting all the gay babies.
Then the test/cure will be available in the US. Then the fireworks begin. What to choose ? Choice ? Abortion ? Gays ?
PC = Pro Cweer?
