Hmmm....I'm not so sure I agree with pleasantness and positive support being a specific issue, especially here at PC.
I, for one am not about to change how I support folks here unless I get a whole load of pm's from people telling me I am too nice or too supportive or too positive. Please folks, if that is the case, let me know and I will gladly review the errors of my ways.
I suppose, that any time there is a false pleasantness, such as the saccharin sweetness, sure, it could be considered condescending....I truly hope that I have never shown that kind of support here.
I don't think that validation has anything to do with pleasantness. But why validate in a negative way? There are always positive ways of getting points across to individuals even if they are in disagreement with things....it doesn't have to hurt to learn that somebody disagrees with them.
Something to think about......
