Far too many people resort to "whatabaoutism" to pass the buck and avoid dealing with today's real dangers associated with the imperialist objectives of the ideology of "the prophet".

Catholics have murdered far more people than throat slitting muslims and genocidal Israelis....Buddhists Hindus Sikhs Shintos and Jains all belong on the list of guilty unforgivable faiths....even the Dali Lama let more of his people be killed needlessly when he escaped his country blathering pacifism instead of negotiating with Chinese invaders

You need to look into the history. Christians did and do kill each other. The Catholic church went threw the reformation where it split into Methodist, Church of England, Lutheran etc, etc. Many people died during that time. When Mohammad died one part believed that his grandson was the one to follow and the other did wanted to follow someone else. Not that different from Christianity. By the way the Spanish inquisition lasted over 600 years and then we have the knights of St John who went and slaughter in the name of the Christian religion. So yes the Christians do a lot of killing.

Perhaps the point of the post could have been stated more explicitly: It will be a historic blunder (IMHO) if tensions between the two Irish nations sabotage Brexit, and the people of Britain thereby fail to regain independence from the dictates of the European Commission.

My friend, your historical perspective seems to be viewed through cracked lenses.
Numerous wars and other struggles have erupted over the Reformation.
The Irish situation is complex, folks tend to forget that the historical religious dimension is three-cornered.
The Irish have often been under valued: a country that can deal with distances in kilometers, speeds in mph, gasoline sold in litres, fuel consumption measured in miles per gallon and two currencies (if my memory serves me correctly) could probably solve this problem.

My question to you is, why are you trying to figure out the motivations of the delusional?
The "christians" aren't any less violent and/or irrational than the islamics.
