You make some very good points. As I said before, I think most would have to be looked at and dealt with individually. And certainly NEVER getting rid of "Gone With the Wind". It may not be an accurate representation of slavery at the time, but it certainly doesn't make it look pretty. Me personally, I am in favor of getting rid of the statues that are of people connected to slavery. The point of a statue is to honor someone, those people should not be honored. (My opinion

)
All of the important aspects of this country's history simply cannot be taught in schools. There isn't enough time. How it is decided what will be taught and what will be left out is, I think, determined at the state level. Unfortunately I guess it falls on the parents to supplement with what they want their children to know. Statues aren't going to fill that void.
So many on here keep speaking of finding the good in people. Well I see the good in those that knew, even in the 30's, that racism was wrong.
Edited to add: I remember a story from when I was a kid. My father was a racist. At a very young age I knew he didn't like black people (or Jewish people). At 4 (1967) I started kindergarten and my bus driver was a very sweet black man. I really loved him. I remember giving him hugs. I knew my father was wrong - I didn't have to be told he was wrong, even at 4/5 years old. Were there other outside forces that influenced me way back then? I don't know, maybe. But I remember very clearly knowing that he was wrong. That's all- just sharing a story.
