I'm about as white as white gets. My parents are judgmental (as am I), but not racist. I grew up watching shows like Sesame Street, Reading Rainbow, Little Bill, Dora the Explorer, and other shows full of diversity. The characters of a another race were never something that occurred to me as being different. Seeing all people as equals came naturally to me, but I was raised on the importance of acceptance. ...but that also leads me to be puzzled as to why people (*cough* Disney Channel *cough*) always feel the need to throw someone of every race/ethnicity into a TV show simply for the "diversity".
Anyway, for me, the color of someone's skin doesn't usually play a role in first impressions. I can only hope for the same treatment in return. What does play a role is appearance and behavior-- but that goes for anyone, regardless of race. I'll always judge the person as an individual, but I will admit it may happen more so with certain races. Yes, I pull out my judge-y eyes at times, but it's human nature. I do my best not to unless I truly feel the need to exercise caution around the person.
