One of the HN rules, and one that I think would vastly improve on line discourse if others followed it. I have to go on FB from time to time (since that's where a community I follow is based) and it's horrifying how quickly and often things spiral out of control, when the protagonists are probably pretty OK people IRL.

Even if someone is being a jerk, responding in this way can often make them pull their head in.

I wish I was better at this.
