For anyone too lazy to watch the video,

Ron Paul wanted to vote to end Jim Crow laws. Chris Mathews sighs dismissively when he says anything libertarian sounding, and just keeps saying "what about all the racists in the south". Ron Paul says it was all government mandated racism to begin with and everything got better due to getting government out of enforcing segregation.  He believes the rest of the civil rights act was another step the government took putting us on the road to totalitarianism.

Good find Flippro.
