I don’t think they’re trying to figure a way out. And I don’t thik they’re all that worried about violence either. There was very little violence against Protestants in the south when the Brits left there. Even today the Protestants in the south control many of the financial institutions, industries, etc. If there is violence in the north, it will be because the Catholics have been poorly treated for centuries (with Bloody Sunday an example of such treatment).
I don’t think they’re worried about violence against the protestants. It is the protestant paramilitaries attacking Catholics that they are worried about.
