"regional discrimination" in the east and west

[mr tin]

As Taiwan expands ties with the mainland China, Taiwanese negative attitudes towards the Mainland Chinese seems to grab the attention of Chinese media now. In recent days a lot of complaints have been shown up in Chinese forums. Many Taiwan's news programmes were posted to show how they teased their mainland counterparts. Some Mainlanders were furied about the biased comments from Taiwan. They have the reason to be upset, but these regional discrimination are common even in China herself. If you're in China, you possibly hear how Chinese talk about Hunanese. It's obviously not racist, but it also advocates hatred and biases towards "outsiders" and push their own regional pride. What I'm wondering is that in some western countries, it seems common that people from one city to tease countrymen from another part of the country too. Did they see any serious regional discrimination due to that? I guess the law for racial discrimination don't apply to these cases, how did they deal with it?
