Only a privileged white Democrat from the suburbs who knows nothing about African-Americans would claim conservatives are more racist now than when it was basically legal to kill black people 55 years ago. Please log off, renounce your citizenship, and move to Antarctica
Racism got very very subtle after the 60s, but then having a black president for 8 years scared the crap out of white people so badly that racism is becoming less hidden and less taboo. Hence why the Nazis are back and white supremacist hate groups have doubled and alt-right sites that had 10,000 members 15 years ago now have 10 million.
America didn't become more racist because we had a black President. The racism was always there.
