C'mon, NDD. That is an advocacy site. I don't care either way, but it seems pretty clear to me that there is research going in both directions and it is at least an open issue.
Have you ever asked a homosexual whether they feel they have a choice about their sexual preference? I've spoken to several who said that they would prefer to be straight but just can't change how they are.
IF this is true, the question seems to me to be whether homosexual conduct is something bad like bestiality or incest, or something that should be tolerated to some degree. Just like the Team Sergeant said.
