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….
The other point of contrarianism is that, if it’s well done, you assemble a whole load of points which are individually uncontroversial (or at least, solidly substantiated) and put them together to support a conclusion which is surprising and counterintuitive. In other words, the aim of the thing is the overall impression you give. Because of this, if you’re writing a contrarian piece properly, you ought to be well aware of what point it looks like you’re making, because the entire point is to make a defensible argument which strongly resembles a controversial one.
So having done this intentionally, you don’t get to complain that people have “misinterpreted” your piece by taking you to be saying exactly what you carefully constructed the argument to look like you were saying.
