I was being generous. :)

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.)
