We don't need such inflammatory and obviously unfair comments like this on Hacker News.

I really like what Scott Adams says: it's something like "People aren't idiots, they just experience bouts of idiocy (some more often than others)."

Yeah, I get your point about the hivemind, but I think it's less damaging to see downvoting as being about the comment, not the person. iow, don't take it personally.
