I don't think anyone is saying racism is non existent, but the voting barriers, slavery, and segregation is over.
Racism no longer exists in the US. Just ask Cliven Bundy, or Donald Sterling.
People saying and suggesting that the only reason a black teenager was shot by a cop was because of racism is beyond ridiculous. The fact that he was black is clouding the judgment of so many people and making them jump to conclusions that are a stretch at best.
