I'm always conflicted about interesting comments which link to something I read and learn from, but which are needlessly insulting. The grandparent linked to FightingAging.com and I read the article and clicked on some of the links and found it informative, though not convincing. But I cringe when he says, "Nonsense about antioxidants in the diet is exactly that: nonsense."

So do I upvote because I learned something from his comment, or downvote because his tone degrades the quality of discourse on Hacker News? Clearly pg says "downvote", and I often do, but I'm always on the fence about it.
