I don't remember the incident, but I wouldn't assume Williams is racist from that incident alone (maybe there's more).    Lot's of people did not like Obama pushing the boundaries of executive orders.    A guy like Williams is more anti-government and dislikes government power over his personal decisions.    Hitler is a sign of authority and control and really represents an amalgam of sins, the symbol of all things evil.        Williams may be racist, but I don't see the comparison to Hitler being motivated by race?   I could be wrong, only Williams knows for sure.
