Has anyone just tried smiling and being nice? Works for me most of the time. It's harder on the internet though...
Humility, humor, and humanness.
Impossible on the internet. No one see the nonverbals.
There's a nod of acknowledgement that people can give to say there is no threat here. Its sorta a simply eye contact, smile, nod, and look away without breaking stride.
In training I find if I don't take an offensive or defensive stance, no one attacks me. There's no "go". Of course some of my friends know me and attack anyway. Same has work in other contexts as well.
