I could as easily claim that Tory = intelligent enough to know that every Labour government since Attlee left the scene has done its best to destroy the country and come bloody close to succeeding

I actually took you to be very old, Don, but you're clearly not old enough to remember that it was Labour who gave us the NHS (OK, Atlee, but the bloody Tories would never have done it!), Labour who gave us comprehensive education, Labour who developed the welfare state, Labour who, even under Blair, not exactly my favourite man, slashed hospital waiting lists, revolutionised nursery education and introduced the minimum wage. And that it was the Tories, under Thatcher, who destroyed the industrial base of this country, threw millions on the scrapheap, wrecked whole communities in working class areas and deregulated the banks in a move that sowed the seed for the present crisis. Oh yes, Labour didn't exactly put it all right, but the analysis represented by your sentence above is, well, a quaint view of recent history, to put it mildly.
