Heard the maxim ‘you can disagree without being disagreeable‘? RBG is noted for stating something to that effect, as is Obama, and perhaps several other cool-headed thinkers. For whatever reason, the saying has been rolling around in my head all week. If I place it side-by-side with my mother’s advice, ‘if you have nothing nice to say, say nothing at all,’ there appears to be a gap. How does one learn to debate hard ideas if one remains silent? Or take inconsistent data and view it from multiple angles? How do we disagree and still communicate? It is far larger than remaining quiet, isn’t it?
