The guy is pro-palestine and defended Marine LePen over something in 2002. This sounds like a non-story to me, frankly.
Is it possible that the guy could be defending Palestine and, at the same time, have sympathies for Nazi propaganda?
After-all, Hitler himself has good relations with the Arab and Islamic world.
