Yeah, kids pick up on cues from the people around them. Or just don't like differences.
I remember in third grade, a girl had just moved into town and was in my class. One of the first things she said to me was "I've never seen a black person before." I told her I was brown.We ended up becoming best friends.
Has anyone ever known a pet to be racist? I swear one of my sister's dogs is.
My Miss Chicken is 'racist' but only to other cats not to people. She only like other cats if they are all black like herself.
