I don't think there's anything wrong with being proud of your race/s per se. I do think there's something wrong with spiting other people solely because of their race or skin color. Personally I'm not ashamed of my race, but I'm not gung-ho about it.
My blood, like most peoples, is mixed. As far as I know I'm Scotch-Irish, Cherokee(My great grandmother was full blooded, so I'm 1/16), and possibly Welsh blooded. I've got a few famous people from the past in my family tree, like Ulysses S. Grant, and some famous hell fire preacher I forget the name of. I know next to nothing about my dads side of the family, which is where the Cherokee bit comes from. His real dad abandoned them when he was little, his step dad was a Hitler youth and abused him, his mother is/was blind and didn't do anything about it, so like I said in another post, our family's not tight.
