Who gives a shit what colour someone is? Pink, brown, yellow, tan, purple with blue spots -- it's all bullshit. Just another way of labelling people, putting them in little pigeon-holes. Same that goes for the crapshoot that is religion -- Sikh, Muslim, Jew, Christian, whatever: just more labels to apply to people.
I don't know any "black people" -- I only know individuals. If they're friendly towards me, I don't care what shade of human their skin is. And If they're not friendly, or are people I don't know, then I care even less what colour/race/religion they are.
