My mom, for most of her life, was a Holocaust denier. And it was terrible for the entire family to have to deal with until, finally, a couple years ago, we had an intervention. And we had a rabbi come into the home, had him walk her through the history of the Jewish people, and then he made her watch "Schindler's List." And after that, my mom did a complete 180. Now she can't believe it only happened once.
