I didn't say that HN was apolitical (an impossible state!). Rather I'm making an empirical observation about the users who complain, as you have, about how HN is biased in favor of the opposite side.

What I'm saying is that your perceptions and the perceptions of your opponents are the same, except for the high-order bit (the political direction you favor) which is 0 in one case and 1 in the other. You can pick whether you'd like to be 0 or 1 :) - apart from this, your perceptions about HN and the style of commenting are so similar that one cannot but conclude that some common mechanism underlies them. Whatever that mechanism might be, it can't be HN's bias, since by definition there can't be two opposing biases.

The public data is already more than sufficient and no one looks at it, except to bolster what they already believe, indeed are certain is obvious.
