I sometimes did work for a lovely old couple who at times needed repairs done around their home. My wife and myself spent time with them, having tea and crackers from time to time. One day the husband and myself got into a conversation and he clearly showed himself to be a holocaust denier. It was upsetting to hear this from the mouth of someone I liked. I quickly changed the way I thought about him and as time went on I couldn't stand the thought of being in his presence. I did some research on his last name and it was the same as a family owning a major German industrial corporation involved in all kinds of war manufacturing during the Nazi era. Maybe just a coincidence, maybe he was a relative, maybe a former SS. Who knows? But the thoughts do run through your mind.
If you know or knew a holocaust denier, how did you feel about them?
