My dad sometimes.....
My dad has a strong dislike of arabs and that's being polite about his feelings. He always goes on about how they own and buy everything up and how they aren't to be trusted and want everything for nothing. My dad is a super proud Israeli however what he won't tell you is he does have persian ancestry too and I believe another group. He always conveniently leaves that out and gets mad when he's on one of his tirades and he's reminded that he's one too. Last time he was making comments my little brother mentioned it and he got mad and started saying well no no no. It's like ok man since you know everything and are always right.
