I’m no expert in Irish history, but I do know that the root of modern conflicts were planted in the 17th century, when the English colonized Ireland, and native Irish Catholics were displaced by grants of land around Ulster to Protestant invaders. This is a problem that has simmered for centuries and erupted in the Troubles and is still a huge political issue between Northern Ireland and the Republic of Ireland.
OK, I’ve exhausted my knowledge of the history of the region, but as an American, it is my right to be oblivious of the concerns of foreign countries. Wouldn’t it be tragic if an Irish person were to forget the history of their country?
Behold, Glinner:

Graham Linehan: ‘Colonialism’, another American obsession. The Irish Left doesn’t have a single thought unless Americans had it first.
Gosh. Did American liberals invent the IRA?
