Here are some more.  Maybe we could have statues of people being lynched.

Maybe this is why Germany doesn't put up statues of Hitler, because this kind of thing is what the Nazis did.  And they actually understand how creating monuments to monsters, no matter how charismatic, actually promotes monstrous behavior.  

Maybe our problem is that it lasted for 300 years, and so it's kind of hard to look at it for what it really was.   Personally, I was a teenager when segregation became illegal, so I remember Jim Crow attitudes.   

Dear me, I'll just have to keep looking to find what it was I missed.  I noticed one thing; in looking at hundreds of old photos of slaves and black people in the south, they never smile.  You can see the pain in their faces.
