Tribes of left and right tend to buy the shop. They take their politics table d’hôte, not à la carte. Those on the left are for more public spending, higher taxes, no war and a tolerance of scroungers, those on the right the exact reverse. Once they have opted for Labour or Conservative (or the obscure freemasonry of liberal democracy), they surrender their political virginity to the party line, lie back and enjoy it – usually for life.
These debates always turn into pleas for liberal tolerance, for a respect for other people’s opinions, drawing strength from Stephen Pinker’s thesis that, whatever else is amiss, the world is becoming a less violent place. But tolerance is itself a privilege of security. Intellectually it is appeasement. I do not want to tolerate those who disagree with me, I want to persuade them they are wrong. Haidt may cry, “Why can’t we all just get along?” The answer is we can’t. The best we can do is not murder each other in the process.
