Crossing into personal attack will get you banned here, regardless of how wrong someone is or you feel they are.

I'm not going to ban you because we haven't warned you before this thread, and because you've posted good comments—but I've also noticed other cases where you broke the site guidelines in previous threads. If you'd please review https://news.ycombinator.com/newsguidelines.html and stick to the rules when posting here, we'd appreciate it.
