Unfortunately, this kind of thing makes it on to HN. That's inevitable when a forum has millions of users, anonymity is ok, and the topic is divisive. We do what we can to try to convince people to follow the rules (https://news.ycombinator.com/newsguidelines.html), and we ban accounts that violate them repeatedly.
