Even on the internet and only in text-based communication, it is possible to address people in a way that is respectful. For example, actually reading what oneself is about to post, thinking about what might trigger what kind of perception. If I want people to answer my question, I ask politely and try to not be a dick. You get what you give. And from what I experienced so far, the greens and yellows are normal mortal humans like anyone else here. Direct approach was always successful in my cases, as people explained me their points of view. And then they started sending me weird pictures via Skype.
