"homosexuality is almost totally environmental"...
... thanks - probably - to God given environmental genes.
Prejudice reigns when it comes to homosexuality.
So, disagreeing with you about the origins of same sex attraction is “prejudice”? Are you sure you are on the right website, because that sure sounds like a liberal talking.
It’s no more prejudice than your prejudice (I.e. An opinion based on what you want to be true rather than what is true) that homosexuality has a genetic component. There’s no such evidence for that, either. So stop being prejudiced and wait for the evidence to come out....
