"Had the colonists not practiced terrorism agains the British, we would still be British today. The Northern Ireland Irish want what we have and what they Republic of Ireland has....freedom from the British. Any of us can understand that as Americans."
The problem is that "the Northern Ireland Irish" are not the homogenous group you make them out to be. If it were a simple matter that all the people in Northern Ireland wanted to become part of Ireland, or gain independence, then it would be easy to resolve the issue. But in fact there are two communities, one loyalist, one republican. You're oversimplifying.
"Had the colonists not practiced terrorism agains the British, we would still be British today..... Any short course on British history proves that that's all the British understand."
I know you're playing devil's advocate, but you seem to be justifying terrorist atrocities. So blowing up a shopping mall and killing innocent British civilians, including children, as the IRA did, is a justifiable act? Presumably destroying the World Trade Centre can be justified as "the only thing Americans understand". Sickening.
And the American colonists were? You missed the entire point.
