You don't have to have sex to reproduce. You do need the sperm and egg, but not actual sexual contact. Some reproduction is um handled with the intervention of a third party.

But does that mean he thinks it's not a "lifestyle choice" but genetic or "gods will"?

The "reasoning" goes something like "Some people are born with a predisposition to be alcoholics. That doesn't mean they have to act on it."

Of course, homosexuals are not born with a predisposition to be homosexuals. They are born homosexuals. Hence, the quotation marks around "reasoning."

I can never follow the twisted logic!.....

about yourself. A lot

Logic implies rationality and deduction or reasoned inference. Crazy Uncle Pat just pulls shit out of thin air. Only those who share his delusions can make sense out of his inchoate ramblings.

their guy's anti gay rhetoric sounds exactly like Pat's. They seem to think it is very different. But it's not.

eaten more Cornbread as a kid, he might have chosen a decent profession ...

If there was a "gay" gene, Pat would be right, and it would certainly be bred out of existence within two or three generations. But the true genetic nature of homosexuality is much more complicated than that.
