As a whiteman, I think it isn't my place to decree what constitutes an 'uncle tom' or not, and frankly I think anyone who does should know their place and concentrate on our own races problems. The one who annoys the most who does this is cenk from the 'young turks' you tube channel when he calls out a black person (always a conservative) as an 'uncle tom', what does he know about being black? And he always covers himself by involving that black guy with the dreads in the discussion. That guy must love his pay check, ,I would have chinned him by now.
