Seriously, though, while I will readily admit to being irked sometimes by the Guardian's tone or editorial stances, this is absurd. If you react like this - subject line and three quarters of your post ranting about the Guardian, only one paragraph discussing the topic at hand - to an op-ed that just so happens to be published in a newspaper you don't like, you maybe need to consider cooling off a little.
As I said to AA, while you of course have every right to rip into the actual author of the piece if you think he writes nonsense, ranting about the Guardian makes no sense when I'm the one who showed you the piece.
One doesn't have to take them at their word to negotiate with them. Look at Northern Ireland - even a limited amount of mutual trust can take a long time to build, and can very easily vanish again. But the current situation wasn't moving at all, so you'll forgive me if I'm positive about one side taking a public step towards peace. I believe we've already established I'm generally a more optimistic person than you are...
