Humans are tribal by nature. We tend to look at those from other tribes with distrust. This is observed all primates.
My "tribe" has members that are African American as well as folks of Asian and European descent (I, myself, am a white mutt with a splash of middle eastern among other things). Caution regarding strangers is natural, true, but race has little to do with that. Family is family regardless of race.
But if I see a group of young black guys dressed up like gangstas and I'm alone and it's 10:30 at night, you bet I'll avoid them.
Alright. Let me ask you this... If you saw a group of young white guys dressed that way when you were all alone at 10:30 at night, would you avoid them too? What about Asian guys? Honestly, if people look like they are up to no good, then will you really be avoiding them according to their skin tone?... =/
It does hurt terribly to be hated for race, but I've encountered so much obnoxious arrogance from black people that I've become predispositioned against them.
Hmmm... Just curious, but have you met many people of African descent from other countries (especially from the African continent)? Would you assume they would act the same way? What about African Americans from other states? People who live far out in the country? Maybe folks who come from different cities?
People often forget that this country is a country of many different cultures and sub-cultures. An African American guy who grew up in Detroit, fighting to survive on the streets, is likely going to have a different outlook on life than one who grew up in the relatively uneventful suburbs of Portland.
