I understand how frustrated people can get in WW (so often I am that frustrated person
) and I think that this perhaps is a particularly frustrating game since there are so many unknowns and the only clues are peoples "attitude" or way of speaking and there is consequently a risk things can seem more personal. Also with the role play it is perhaps harder to phrase things so it criticises the behaviour.
I do remember I gravely offended someone for saying something they did was stupid - I never intended to mean that they were stupid, only the action, IMO, in the context of the game - an important distinction that it is easy to lose. It is just a game but there is still the possibility of sports injuries!
