Maybe we or I see what we don't like and concentrate on that more than is necessary, which skews our bias. Its very easy over an internet forum to only see flat words and no emotion or context behind them. Which means the response can be sharp, especially when it triggers emotion and tries to funnel understanding into text. I can't feel what you are trying to convey to me when you reply. I can only think, orange, rational, from the text sent.
Voice helps bring context as does seeing the person talk, and even more being with them or knowing what is going on around them. If I heard your voice or knew you, your community and your backstory I would much more easily demonstrate green to you.
On an aside, the internet initially was designed purely from a orange perspective by orange thinkers. Forum software designed in a green way might look and operate differently.
