This breaks the HN guidelines by calling names and turning an otherwise substantive (indeed, correct) comment into a personal attack. Please don't be nasty here, regardless of what the other person did or how mistaken they are. We detached this subthread from https://news.ycombinator.com/item?id=11297077 and marked it off-topic.
