I have almost no knowledge of this.
I have only ever seen one small Orange parade and it was a quiet Sunday morning without even a band.
(One of the marchers was the host at our B&B. A very nice couple.)
I agree with all your last post Jim, except I do not understand why you say they parade to "prove their superiority."
Is that not just how you choose to see it?
It is just a band and people walking.
It is their one way of celebrating their cultural identity. Presbyterianism has deprived them of music, dance and song.
They have their bands and they march and they love it.
Loyalist do not have the monopoly on hate and intolerance.
I could see plenty of that in those republican rioters.
