@Cantab - remember Sinn Fein grew out of the IRA
I don't remember the point at which Sinn Fein denied the right of England to exist.
I don't remember the point at which they refused, outright, to negotiate in any way with England because it existed.
I don't remember where in the IRA's constitution it explicitly calls for the destruction of England.
I don't remember the point at which they encouraged bombings without warnings (remember IRA bombs always had warnings because the IRA didn't want indiscriminate killing, it's bad publicity. Whereas killing Jews in the Middle East is good publicity unless you're Jewish).
I don't remember the point where they were offered a place in government and refused it because the English would still be involved in Northern Ireland
I don't remember the point where Iran and Syria shipped medium range rockets to them to fire indiscriminately at Liverpool (the equivalent of Ashdod)
I don't remember the point where England withdrew entirely from Northern Ireland and the IRA denounced it as an act of aggression.
But perhaps you do.
Try visiting a country in the middle east and telling people you are Jewish (not Israeli, Jewish) and see their response. From Morocco in the west to Malaysia in the east and right across Arabia and the middle east, the Jews are despised and people do not draw much if any distinction between Jews and Zionists. These wonderful countries pour billions of the oil money we pay them, into movements such Al Quaeda, the Taliban, Hizbullah, Hamas, Fatah, the Brotherhood and various other extremist movements that would otherwise be starved of funding by right-thinking people. They in turn spend millions on the poisonous films and "documentaries" and press releases and PR work we see in the middle east every day, denouncing Jews (and Zionists and Israel).
I am not going to defend Israel at this point. I am just going to say that I don't think the analogy between Hamas and the IRA is fair on either party.
