Apparently now exercise in an exercise in "white supremacy". I guess somebody had better warn all those wonderful black athletes out there about this. With this logic, Jesse Owens wasn't a hero who destroyed Adolf Hitler's attempts to portray Germans as a "master race", but rather someone working to further enshrine Jim Crow. I'm guessing this would have come as something of a surprise to him, to put it mildly.
Really, one has to wonder whether progressives really believe the things they say, or whether they're really Klansmen in disguise trying to get black people killed by worsening an already horrific rate of cardiac disease and diabetes. The more I see out of these guys, the more that second hypothesis makes sense.
