A story from Australia, which is sort of relevant:

Old man in a restaurant with his family and he's getting angry, and he shouts out. "HOW MANY TIMES DO I HAVE TO TELL YOU - I CAN'T STAND ABORIGINES"

People around look shocked. Family looks mortified. "Calm down Dad" says the son. "Everyone is looking at us."

"I don't care - it's the truth. I hate aborigines. I think they're poison."

"That just isn't true, Dad. And anyway, the word is 'aubergines'."
