Homosexuals better hope it is not genetic cuz there will be an abortopalooza if homosexuality can ever be determined in the womb. What a conundrum that will be for liberals. Although they don’t seem to be too concerned about gender selective abortion. I guess the rite of abortion trumps all other political correctness.
They will just declare that any test for a gay gene is a hate crime. Any scientist developing one will have all his grants cancelled. Any company producing such a test will be driven into bankruptcy. Any lab processing such a test will be burned.
This is known in advance. Nobody will produce such a test.
