That really sucks that you and the other people in this thread have to deal with this shitty behavior. Being a short white woman I've never had to deal with racism (minus the people who think it's okay to start spouting racist bullshit around/to me) nor have I had to deal with people seeing me as threatening just from the way I look (their mistake, heh).
I really hate that people can't just judge others on their actions and how they treat those around them. That's how I treat people, you're my buddy, or at least non threatening until your actions say differently.
I imagine it must be insanely difficult to maintain a world view like mine if you're often exposed to the worst other people can say/do just because you look different than them.
Also: you beat my high school GPA by .15
