On what basis do you make the assumption that the people killing one another in Northern Ireland were “good religious people”? What makes you think the people killing one another had even any religious beliefs at all?
You fail to understand. In the Northern Ireland conflict the label ‘Catholic’ or ‘Protestant’ had nothing whatsoever to do with the person’s religious beliefs. There were ‘Catholic’ atheists, and ‘Protestant’ atheists. Everyone in Northern Ireland (even Jews) were assigned into a particular ‘camp’ (Protestant or Catholic) regardless of what that particular person believed. Religious belief had absolutely nothing to do with it. Once assigned a camp (which you had no choice in the matter) you could never leave (and stiil can’t) that camp (regardless of what you happened to believe, or not believe). The labels ‘Catholic’ and ‘Protestant’ when used in relation to the Northern Irish conflict have nothing whatsoever to do with religious belief.
The motivations for how people acted had absolutely nothing to do with anything regarding religion. And how do you account for the role of the British Army in this? Where they acting as Protestants fighting Catholics in the name of religion, even though they will have had English Catholics in their ranks (as well as many atheists, just like the Republican and Loyalist paramilitaries)?
Believe me, if you think that the conflict in Northern Ireland had anything to do with people being motivated by their religious beliefs (or anything to do with their religious beliefs) then you really are talking out of your backside.
