The old IRA fought British soldiers. They did what they had to do against the likes of the Black and Tans and in some cases it was gruesome. However, there was a campaign of hate against the Irish people and the IRA stood up to them through the use of guerilla warfare to defeat them.
I have a huge degree of sympathy for how northern Irish catholics/nationalists were treated after partition and I can totally understand how thousands of young men in the ghettos of Derry and Belfast would end up in the IRA of the late 60s/70s/80s. However, it still doesn't take away from the fact that countless atrocities were carried out against Protestants up North in this period against the innocent. Often, the IRA indiscriminately bombed such as in Omagh where many Catholics were killed. I cannot bring myself to sing and glorify about these scumbags.
When I lived in Guildford, I just missed the bombing by hours. The pub was a known military pub, but alot of Irish navvies like myself and Irish nurses would often be in there. I could so easily have as well. They didn't give to much of a toss though did they. Anyone who is old enough to remember what it was like to live in mainland Britain after the bombings will tell you what it was like. You found yourself trying to justify what the IRA did in the context of what the British had done to us for centuries, while at the same time feeling shame for the loss of innocent men, women and children. Try tell that to the bombers who had probably fled back to their safe houses in the South of Ireland, while you and your mates were being interned for hours and questioned about being part of the IRA.
From my experience, the modern IRA are drug dealers and involved in other criminal activity. They are so far removed from the IRA of the past, it is not even funny.
It is true that very very few of our fans sung and glorify about the IRA and long may this continue. We have the best fans in the world and this is why the Poles want to play us in a friendly.
