Serious question: do people want HN to turn into a safe space then? I always preferred the blunt tone of the forum, because in practical terms you can flesh things out faster that way, and anyway it's literally pixels on your computer - they can't physically hurt you. Hell I'm even guilty of fanning the flames further sometimes, but again I always thought it's part of the conversational culture here in order to gauge every possible angle to a subject as effective as possible.
I certainly don't want the "forced nice" tone being policed here. It will likely kill the entire charm of HN.
