> expressing ones frustration is usually possible without doing that
It is possible, but it is very hard to do. Especially when you feel that you are being belittled when the developers just tell you to deal with it, you will eventually like it. That causes more hostility than frustration.
But I agree, keeping emotion out of the discussion is probably more productive. I know I have said a lot of things about Gnome3 out of emotion than anything else. But it just feels so good to do that :-)
