Growing up, most of the black kids in my high school were the children of Somalian or Nigerian immigrants. I did not have an issue with them, but they were often very shy and usually kept to themselves. Non-African black kids in my school were quite rare, but as I was in a small high school in a medium-sized town, the latter seemed like they were spared from trying to act like hoodrats and wannabe thugs.
However, the worst "black" people I had to deal with in my school were wiggers. My school was infested with them, as many of the white kids tried so hard to copy every negative stereotype of black urban culture that they were constantly making life hell for everybody else by being confrontational and obnoxious, engaging in casual vandalism, or ripping off people's stuff and breaking it.
Without wanting to powerlevel too much, I had a job at a plasma donation center once in a big city in the Midwestern US, and you saw a lot of all sorts of interesting donors there. I do not know what it is about black culture in a lot of highly-urbanized areas, but we have had to throw out so many black potential donors for trying to donate plasma while being too high to speak, blasting rap on the donor floor as loud as possible, getting into shouting matches or fights with staff or other donors, or just being generally rude and unhelpful when we were trying to ask them questions or explain the process of plasma donation...and these were often people in their 30's or 40's.
I mean yes, I get that aspects of their lives probably suck if they are that desperate to get money for plasma, but we have had to call the police so many damn times on this demographic for the threats they made to staff or the fights that they would pick in the parking lot that it was ridiculous. I mean yes, we had more than our fair share of "urban" white trash, but why the hell did it always seem like black donors acted the worst?
I do not hate black people, but I do hate whatever cultural and social animus that causes many of them to act like the above, and I am sure that it must be very embarrassing if you are black to have to put up with the social pressure to conform to the same behavior as well.
