The 'North' is a Tinderbox just waiting to explode, the Proddies hate the Catholics and the Catholics hate them back just as much.
It won't take much to set fire to that Tinderbox, even a few years back when they changed the times of the Union Jack being flown over Stormont, it was enough to bring the Proddies out on to the streets to Riot.
The Queen's visit a few years later brought the Republicans out on the street to Riot.
So they don't need a really big excuse to Riot !
If there is a Hard border, then the Republicans will Riot and Riot Nordie style.
If there is Not a Hard border, then the Proddies will Riot and Riot Nordie style.
Either way, there will be Riot's !
I'm just glad I'm way down South here and let 'em at it !
