Well, I suppose it depends on how you define “denominationalism”. Protestants may not actually have called for separate schools for their children and Catholics but they most certainly did campaign to keep religious instruction in the schools and for “Protestant teachers to teach Protestant children”. See Michael Farrell’s Northern Ireland: the Orange State (p. 102) and Jonathan Bardon’s A History of Ulster (pp. 503-4) (the latter further citing D.H. Akenson’s Education and Enmity: The Control of Schooling in Northern Ireland 1920-50). And unless you’re suggesting that they thought Catholics would happily send their own children to these schools, effectively this amounted to a call for denominationalism.
I actually said “that much of a difference”, which is somewhat different to none at all. Having attended integrated schools in the US myself I’m well aware of the fact that they in and of themselves only go so far in promoting tolerance and understanding; racial (or in the North’s case religious) prejudice has ample opportunities to rear its ugly head when the children leave their integrated schools.
And of course, Northern Ireland has the additional dimension of a substantial proportion of its population not recognising its legitimacy in the first place. Most people involved in physical force republicanism will tell you they have nothing against Protestants personally, they just don’t think they have the right to dictate which flag flies over the Six Counties. Integrated schools would not turn republicans into unionists.
True, but the old axiom about polls only measuring what people tell pollsters is always particularly appropriate in the North’s case. Just because people believe in integrated schools doesn’t mean they’d want their own children to go to one. It tells you something when even the (pro-integration) Education Minister is only willing to set a target of 10% attendance at mixed schools.
Although I don’t think attitudes have changed as greatly as you seem to think, please note that nowhere did I say that the 1930 Education Act is evidence of what people think in 2004.
