Earlier quoted context omitted.
I down-voted this comment for its tone. This is a thorough and well-informed rebuttal of the parent comment, but it's buried under an unnecessary layer of sass and sarcasm. I appreciate your passion, but we can do better than this.
What is thorough and well-informed about the comment? Genuine question.
People new to HN need to be introduced to the culture here without being deterred entirely from commenting again in the future. This way, others can engage the new user on the merit of their ideas (right or wrong) rather than on their tone.
Generosity notwithstanding, the comment did contain a grain of truth (heh) in that a good strategy for cutting through the contradictory tendency of dietary science is focusing on what works for many people in practice. (At least, that's what I remember; it's flagged now so I can't read it anymore.)
