Joan Rivers has a message for the folks at the Anti-Defamation League: Mind your own business.

The funnylady tells E! News that the watchdog group has bigger fish to fry rather than calling her out for comparing Costco to Nazi Germany after the warehouse chain giant allegedly banned her new book, I Hate Everyone…Starting With Me, due to profanity.

"Number one, my husband lost most of his family in Auschwitz, so don't talk to me about the Holocaust," Rivers tells E!, defending the analogy. "Number two, banning books anywhere is a bad portent. Number three, the ADL should worry more about the world's attitude toward Israel than waste time and energy on me, because I'm not going to stop saying what I think."
