The whole idea of contrarianism is that you’re “attacking the conventional wisdom”, you’re “telling people that their most cherished beliefs are wrong”, you’re “turning the world upside down”. In other words, you’re setting out to annoy people. Now opinions may differ on whether this is a laudable thing to do – I think it’s fantastic – but if annoying people is what you’re trying to do, then you can hardly complain when annoying people is what you actually do. If you start a fight, you can hardly be surprised that you’re in a fight. It’s the definition of passive-aggression and really quite unseemly, to set out to provoke people, and then when they react passionately and defensively, to criticise them for not holding to your standards of a calm and rational debate.
