I've read the book Uncle Tom's Cabin, many years ago in fact and for the life of me I can't figure out why "Uncle Tom" is a pejorative. He's described as a mature, adult "man's man" who covers the ground walks on. He's the hero of the book who is murdered for helping other slaves escape. So why is "Uncle Tom" a slur?
I'm glad you asked this, because I'm now having fun reading the answers from the same question that has been ask previously. But, you should try that search :)
