Attacking people, getting push back, getting personal and portraying himself as a victim is a pattern that can be found over the last decade. Talking about this pattern is relevant when we discuss the behavior of HN posters here. Especially if Dave provokes this behavior in others with the goal of getting attention to himself. Then people agreeing on HN behavior in the comment of the second submission just play according to the book.
