They all dress alike in plain clothes and all have a similar mentality regardless of which side of town they are on - the rich east or the poor west.
This type of discussion annoys me to no end. Do you know all of these people on a personal level? How do you know that they are all the "same"?
Heck, there's quite a bit of diversity within my own immediate family. We all look and dress alike for the most part, but we are all VERY different.
A community that is 95% African American is still diverse if you look at what's important - what's INSIDE people. Same with a community that is 95% White or 95% Arabic. I get a little tired of the notion that a community is only diverse if it has a bunch of different ethnicities. Who cares what the people look like? EVERY PERSON IS COMPLETELY UNIQUE. Don't make a mountain out of a molehill.
