No you're not. You're simply an idealist a bit. I was too once...a long time ago.
You have described the neighborhood in Brooklyn where I currently live. The Arab Muslims (largely from Egypt and Yemen) have poured into Bay Ridge in droves over the past ten years. They have displaced many middle-class whites in much of the neighborhood, although the people in the million dollar mansions and co-ops near the Narrows seem to be holding out.
Although I enjoy the pastries and waterpipes, it is kind of discomfiting to see women dressed from head to toe in the latest 15th Century fashions pushing baby carriages all over the neighborhood.
