If you choose to label a God given law as predudice, and label people that choose to follow that law as predudice, that is your prerogative.You did exactly as he suggested. He wrote, "But like with what happened with homosexuality... When people quoted the Baha'i teachings, Baha'is had to do some quick thinking to try and not look like homophobics" and you immediately deflected away from yourselves back to him.
Homophobia isn't a splinter. It's a giant sequoia. You marginalize and demonize a large law-abiding segment of society based in nothing more than the belief that some god nobody ever sees disapproves of them for reasons never given - people trying to support themselves and their families and serving their communities just like their straight neighbors whose churches call them sinners who offend their god.
