Here are the guidelines. If you have never read them, read them. Wait for it... It is okay to down vote to express disagreement. The guidelines don't say that. Have up/downvotes become a popularity contest now? Has HN become Reddit Orange? I downvote for one of two reasons: 1) a source or reference is misquoted or made-up altogether. 2) a clear error in reasoning was written (e.g. misinterpretation of the submission of of a stated source). I don't downvote out of simple disagreement. Indeed, I WANT to see well-reasoned arguments that I may disagree with at first glance. Am I alone in this?
