At this point, I think I would say that Uighur communities, like most, are varied in their political views and religious adherence. It spans the spectrum from some activists who would like to see an independent state, to those who simply find it very difficult when elements of their religious and cultural traditions are not respected.
It's a very wide spectrum, I think is the best way of answering your question. It's not a monolithic community, either outside of China or inside Xinjiang.
