Sorry if anyone was offended by my remarks about Hispanics. People who have lived in other cities have said that Pittsburgh is unusual because of the small Hispanic community. It's apparently odd in an urban area.
There are many Hispanics in my sister's Chicago neighborhood, and Chicago winters are worse than Pittsburgh winters, which is saying a great deal.
We have lots of other ethnic groups. I get my pizzas from a place that's run by Turks, and I've bought cherry juice for Hollowfox from the Turkish grocery in Squirrel Hill. There are plenty of Asians. There's a large Indian community, there's even a Hindu temple in Monroeville. I've seen Muslim women, in hijab, going into the Squirrel Hill Library. (Squirrel Hill is Pittsburgh's Jewish neighborhood.)
I worked for the 1990 Census, in Oakland, near the Universities. They gave me forms for non English speakers, in Spanish. I met several Spanish speakers, and people with Spanish surnames. They all spoke perfect Engilsh. The non English speakers were Arabic, Indian, Turkish, Korean, Greek, and Chinese. They didn't speak Spanish either. Those forms weren't a whole lot of use. The 2000 Census offered multilingual forms for assorted non English speakers.
