>> "Maybe this is the catalyst needed to advance the conversation."

I've said this in another comment but I think it is. We now have an issue that will effect all the people in the North and is more important than the usual sectarian divide. If border controls come into place and it starts to effect people's daily lives (e.g. People living in border counties and working on the other side) there's actual a real debate to be had for once. A border poll has already been called for this morning but of course the secretary of state has dismissed it. I think Scotland will need to vote for independence before Ireland has a shot at it.
