Well... James is a pretty sizable sleaze... but just having a collection of nazi memorabilia doesn’t make somebody a white supremacist.
My friend collects this stuff as a way to make money. He buys things he thinks he can turn a profit on and sells them within a few years. He bought a lot of the stuff from WWII veterans or their family members.
A surfboard with an image of Hitler is not "memorabilia." Memorabilia would be WW2 artifacts such as you would find at a gun show. James has gone over the line.
