It's stupid and boorish, but unfortunately not surprising, the way a (thankfully dwindling) number of people define Irishness by the actions of the IRA.
What's utterly unforgivable though (and there was a particularly nasty example of this on the St Patrick's Day thread) is people using the suffering of child abuse victims as an excuse to take a cheap shot at an entire nation. It's not "childish", "banter" or any other such thing, it's horrible, self-diminishing rhetoric of the lowest order. It's beneath contempt.
To those people who continue to plumb such depths: if you ever stop to actually think, rather spout bollox under the flag of anonimity that the internet provides, you'll find that the Irish certainly do not have a monopoly in these parts on either despicable military actions or heinious crimes against children.
Just to clear one more thing up:
More Irish people (per capita) than British do receive a third level education. It's free too, with no student loans to be paid back, ever. (Although that may change soon if Sarkosy & Merkel don't unhand our balls). So perhaps there might be something in the Irish education system that the British could learn from - just as we could learn from your health system, by the way. (Yes, ours really is that bad!). My son, like most of his friends, sat his Leaving Cert, four years ago, at 17, by the way.
