Not long before Donald Trump pathetically admitted that President Obama was born in the United States, two of his white supporters stood outside the Republican nominee s new Washington D.C. hotel and claimed that black people don t work as hard as white people.And that was an incredibly bad idea considering they were standing in a city that would not exist without the back-breaking labor of slaves who built many of the buildings around the city, including the White House.So when these two Trump supporters ran their mouths, Carlos Maza of Media Matters starting filming them just as a black man rode up on his bicycle and informed them of just how wrong they are. You see these buildings down here? Black people built the buildings on slave labor,  he said using Georgetown University as an example.  So a lot of black people have residual anger for their ancestors building this country as free labor. Indeed, white racists would rather pretend black people had nothing to do with constructing our nation s capitol rather than acknowledge that they played a major role.But the man was not finished schooling Trump s supporters. As soon as a white person steps into America, they have an advantage just by being white,  the man pointed out before going on to explain that systemic racism has been built into the system.The Trump fans tried to change the topic by claiming that thousands of Europeans have been killed by Muslims, which is incorrect. Hundreds of Europeans have been killed by terrorists, not true practitioners of Islam.A white people standing by the black man then asked the Trump duo if they have really ever experienced discrimination and they admitted that they haven t.Here s the video via Twitter.Here s a Trump supporter getting schooled on systemic racism after suggesting white people work harder: pic.twitter.com/gbHPkT4A2o  Carlos Maza (@gaywonk) September 16, 2016And yet Donald Trump wonders why black people don t want to vote for him.Featured image via screenshot
