Sexual orientation, like race, is an inherent and immutable characteristic. You may find that “disgusting”, just like white racists find non-whites “disgusting”, and that’s your right. Just don’t be surprised when society marginalizes you and drives you underground, just as has been done to racists. Yes, there are still racists. But they’re not as open as they used to be, because openly being racist makes one a pariah, costs people their jobs, costs people the respect of others, etc. Same will happen to the gay-haters.
