First, we'd be wise to recognize a distinction between communication and self-expression. But remember that Rosa Parks did not spontaneously decide to sit down on that fateful bus. But it would have been a tactical disaster to forward such an individual to symbolize that cause. They would, however, make uniquely unconvincing symbols, at least in the minds of most Vermonters. Emotion-laden appeals get the biggest initial reaction, but it usually fades.
Rational arguments presented by credible sources tend to have the most durable effect.
Think back to the Phelps gang's visit. I know of no evidence that they could have changed many Vermonters' minds. But satisfying though it might be, it would not be very persuasive. So we're somewhat stuck with a choice. Downplaying their existence does, in fact, misrepresent who and what we are.
