I think like he's arguing exactly the opposite, as he's implied multiple times:
> The challenge is the low bar of whether or not a topic has an overwhelming majority of opinion.
> But I'm asking why the person posting believes that the HN community overwhelmingly believes X and their evidence for that.
>> But I'm asking why the person posting believes that the HN community overwhelmingly believes X and their evidence for that.
My read on it is that the person wasn't making an assertion of fact on this, they were making a wry observation that their perception of a prevailing view was the opposite of their parent commenter's perception of a prevailing view, thus demonstrating the hostile media effect in action.
