I think they wanted to see people giving others the benefit of the doubt, instead of making snap judgments. It’s very easy to get into heated arguments online that could be avoided with simple clarification and communication.
If someone is simply bad at expressing themselves, the extra “room” can make all the difference in the world. If they really are a jerk, though, all you’re doing is giving them enough rope to hang themselves. Win/win!
Then again, you’re talking to someone who hasn’t visited Beehaw in almost a year. I don’t know how their moderation has changed.
