Healthy dialectic is made by oppositions that oppose, not hand-wringing centrists who wonder why we can't all get along. Spain has got a right-wing government and a left-wing opposition, until the last election it was the other way round. You've had Blair saying he was an admirer of Thatcher, and Cameron saying he was a bit Blairite, for fuck's sake. Spain is every bit as screwed as anywhere else, or more so, but at least there's a bit of ideological clear water between the two options, it's not occupied by some ramshackle party of bleating sheep half of whom want to run one way and half the other. Just make your minds up which side of the divide you're on and let the Lib Dems wither away. The UK isn't meant to have three main parties.
But the world does move, and its motive power under God is the fearless thought and speech of those who dare to be in advance of their time - who are sneered at and shunned through their days of struggle as lunatics, dreamers, impracticables and visionaries; men of crotchets, vagaries and isms. They are the masts and sails of the ship to which conservatism answers as ballast. The ballast is important - at times indispensable - but it would be of no account if the ship were not bound to go ahead. Horace Greeley
