The original point was minor, if provocative. Unfortunately, though, posting an HN comment about a minor provocation can actually have a major effect on a thread—especially if it gets upvoted to the top, as indignant comments often do. That's why we moderate those and why I replied to you. The fault lies more with the upvoters and repliers than the original commenter, usually—but it's a co-creation. We all need to resist it because it leads to much shallower and less interesting discussion.
I'm surprised point 6 didn't defend into playground name calling.
Grow up.
