Jim,
"These are the ones in Belfast and Derry; they are the most intimidating and they are targeted where they can give the greatest amount of offence; unsurprisingly - it is these that cause the most trouble.

.... all trouble is a response to the provocation caused by the marches and the practice of the marchers who have been banned from marching in Nationalist areas parading back through those forbidden areas when the march has officially finished."

Well Jim, the recent trouble started before the first parade.
A gang tried to attack a bonfire party within the Unionist community the night before a parade.
The big Derry parade was peaceful. No trouble at all.

Jim, you have said that the parades are wrong and should stop, even if they are harmless and traditional celebrations.
Are the dissident bombs wrong?
Should they stop?
