you are jumping the gun here.
He never mentioned sex with a horse - just said the cowboy wanted to marry his horse.

Beastiality is not the discussion - marriage is

How is the horse going to consent, say "I do" Marriage is predicated on Love the man may love the horse but there is no way to say the horse loves the man. I don't know any gays personally, at least ones that I know of. But the last time I checked, I think they are still humans. Incest is another matter and has more to do with health and genetic problems that can occur.

If a boy is adopted and grows up and has sex with some girl and it turns out to be she is his sister is it incest and should they be punished? In many states you do not need a blood test. So I suppose it could be possible to be married and be related.
