Yeah, I know - studies. But anyway, the study I read (and was impressed by) indicated clearly that when people who believe a certain way are shown irrefutable proof that they are wrong, their belief in fact intensifies. This is presumably true of Holocaust affirmers and deniers alike. To the same extent? THAT could be interesting. Another study? I dare you!
