More often then I'd except, black people are loud (I remember someone made a thread about stereotypes that are actually true about two years ago and they mentioned this (EDIT: See below).
More often then I'd expect, black people don't have the same concern for being polite about acknowledging where others are trying to walk/moving over a bit in crowded public places.
Now see, my explanation for this would be that: black people come from poorer areas more often then whites: people in poorer areas regardless of race don't have as much of a concern for certain types of public etiquette: some black people don't have as much of a concern for certain types of public etiquette.
EDIT: Here's the old thread I mentioned: http://www.offspring.com/community/s...ereotypes+true Wow, I actually wrote the same two things Jakebert wrote. Sorry to drag you into this Jakebert, but you have superior credibility on this BBS, so that helps me make my case lol.
