We judge crazy and normal all day long.
A ring through your nose is crazier for many people than one through your ear. To be married as a man with three women at the same time is crazy, but having three girlfriends as a woman is very common. Eating your own dog is crazy, but not your own pig. cannibalism is not allowed, but when a priest in the church says that he is going to drink the blood of Jesus, we find that very normal.
