His perspective challenges many of the facilitation mantras that say: hold your tongue, mind your manners, dial down some of your views, don’t be critical, move towards a win-win situation, compromise and, if you get stressed, take a break and go out for a while. Have a beer!
But, ironically, being polite (or appearing to be polite – ie. passive aggressive) leaves little chance for us to compromise because by being polite we compromise our own views before we speak.
Also, being polite sometimes weakens important strategic dialogue. We worry about being direct and sometimes cloud the importance of the message we want to give by trying to avoid criticism. Others around the table don’t know what we really think.
