but why it's biological? i dont understand. are u referring to genetics, like u dont like ppl of other colour because ur genes are like that?
for me is social, cultural, like u learn to read ppl. I live in Brazil, so there's a lot of different ppl here. if i see a black dude with beat up clothes, all fucked up screaming like a lunatic, yeah, I gtfo. but if it's a black dude chilling and wearing good clothes asking me whatever I answer him on a friendly way.
