This pretty much underlines the difference between the Catholic and the hardcore Reformed points of view.
You'd never have a Presbyterian parade featuring a portrayal of Pope St. Pius V - unless it was in Northern Ireland, where he'd be burning in effigy.
Not really. It actually underlines the difference between those who embrace and live their religion, and those who suffer from and die for it.
Plenty of hardcore Catholics around who are no better than the Ulster brigades.
