Nah, one has to learn to stop caring about downvotes that much. You can very well express contrarian views on HN, and yes, you sometimes have to pay the price in blood^H^H^H^H^Hkarma. Like with all worthy causes. What matters is that people will engage your argument constructively, if you write it in a substantial and civil way.

Case in point: only yesterday 'miguelrochefort had the guts to post advocating a completely contrarian view on privacy[0]. That particular comment, predictably, got downvoted, but it didn't stop a thoughtful discussion from spawning. As long as this happens, HN serves its purpose.

Also, how do you know that people who downvote you are "JS hipsters" and not someone else? :).
