Northern Ireland General Discussion

[Peter the Lefty]

I just have a discussion about NI politics that I thought I'd put here: Why is it that there are no left-wing Unionist and right-wing republican parties in NI?  Surely there must be at least some left-wing unionists and right-wingers who support a United Ireland?  Or are the communities that polarized that they both are also purely on opposite ends of the political spectrum?  (with only one centrist party that combines both of them in the middle)
