Waffling?
Well OK, but I was responding to a lot of posts at once.
My point was
Civil Rights movements arose in both countries
Both were subject to lethal violence from state forces
In US they persued non violence and were successful
In NI the leadership of what became PIRA used the opportunity to enlist the angry young men and began a killing spree out of all proportion (Amnesty International attribution of killings)
The Civil Rights movement was replaced by a movement reviled by most people outside the nationalist community, and a few inside.
