Kieran, that is definitely an artifact of where you live. I have lived all over the US and I have to say if you live south of the Mason Dixon and East of the Mississippi then racism is worse than other places. Northern states aren't as bad (not saying you won't in counter it) but I think they've been a melting pot a lot longer than the south. I live outside of Memphis and I never thought about a person's skin color or ethnicity as anything other than interesting until I moved here. In fact, the first time my child asked me about skin color, I explained it to him saying that it was just like hair or eye color, some people have one color and others another, but we are all the same. Then I moved here! I went to a park with my daughter who was about 4 at the time and was literal scared to the bone by the interest a group of African American boys (of the same age) took in her and her blond hair and blue eyes. By the same token their chaperones told me they were amazed I didn't pack up and leave as soon as they arrived. I have also learned that "yes, ma'm" can be an insult if they say it the right way!
