Then how exactly should I interpret this quote from him?
: “Everything is blurred on what’s right and what’s wrong… Sin becomes fine. Start with homosexual behavior and just morph out from there. Bestiality, sleeping around with this woman and that woman and that woman and those men.”
The fact that he even tries to make any connection between homosexuality and bestiality is what I think people take offense to. I think he should have passed on the subject and maybe just say that he is against the lifestyle and his religion or even say he doesn't know enough about homosexuals to make a sensible contribution to the topic.
You have completely misinterpreted what he has said. No where does he say that homosexuality lead to bestiality. He was asked what was sinful and listed several examples, one of those examples was sleeping around with women.
Again if you're going to go with what you misinterpreted then you must also think he said bestiality leads to promiscuity with women.
