You're not wrong, I'm just surprised when educated people aren't aware of this stuff. Jim Crow was discussed in high school here in the South and there was plenty of opportunity to learn about it in college. The only way people can't know of this is if they haven't actually interacted with minorities that much, which I guess is possible in certain places.

Similarly, this was really great, as it shows the outlash King got when he tried to approach wider social issues as well as the outright hostility against him in places we don't usually consider "racist".
