If you think that the conflict in Ulster is religious conflict, then you are either dumb or uneducated; eg., google for 'Nairac' and note his religious and political affiliations. That thing about a 'religious' conflict is just some stupid shit that the politically correct media likes to spread, rather than telling the truth and saying that it is an ethnic conflict. The Irish are 'Catholics' and the English are 'Protestants'. Usually. But not always. But you do not find many of the English RCs in the IRA.
So no, the man was not killed because he was Catholic, but for being Irish. In Ireland. By the English.
So yeah, let's spinn some dumb shit about religion so that we can feel a little better. After all, it's 2009 and ethnic conflicts within the EU does not sit well with the establishment as it kind of goes against everything that they believe in.
Think that IRA ever fired a shot for greater glory of God? Think again.
