I'm starting to think Turk is a closet Jew. He wish he could just come out and say he was always a Jew inside, but couldn't get out of the closet because of backlash.
That would explain why he's hating on everything Jewish, he has to convince the world he's anything but Jewish, just like someone who's trying to show the whole world they're homophobic because they don't want others to know they're gay themselves.
That's probably why Turk hates Allegri, he reminds him of the Jewish man he once felt in love with, but he left Turk for someone else and broke his heart.
