Holy crap, my new client is a Nazi lover...what to do?

I’m a graphic designer and met with a guy yesterday, who I’ve done work for previously and considered him a good guy. Anyway, yesterday, I had to go to his house to meet with him about a new project he had for me. I went there with my girlfriend and 90% of the time was spent talking about politics/history, rather than the project.

To make a long story short, he mentioned that his dad was in WW2, and won numerous medals. He also said that his dad was one of the US Soldiers who liberated a concentration camp. So, I then said how his dad was a hero and must have seen some really disturbing things. He then told me that his dad always had a hatred for the Jewish people and that Hitler was brilliant and had good reason to do what he did, etc…

I was freaking shocked by what I was hearing! I then told him my dad was Jewish, although he converted to Catholicism (my mom is Irish Catholic). It was amazing to see how his face turned red after I mentioned that. He quickly said, oh, I actually have Jewish blood in me, too, as if that made everything he’s said ok.

Anyway, I gave my opinions on the matter and then told him I’d be in touch about the project. So, what should I do? I was so angry at the time, I was thinking I should just tell the guy I don’t work with ignorant bigots, but now I think I should take the work and get as much money out of him as I can, because I need the work.

Opinions?
