I often take the denial side of the "Americans landed on the moon" argument. It is always fun to challenge people on their long held beliefs and make them rationally defend their position. Do people actually try to defend it, or just write you off? If someone tells me they're a holocaust denier I'm not likely to try to prove it happened. The evidence exists if they cared to spend 5s looking. I'm much more likely to just say, "OK", and then avoid at all costs, since frankly I'm a little afraid to be around people with such beliefs -- since the belief that it didn't happen is also strongly associated with "and if it did, it would have been justified".
