John I totally agree that its the mildde group, onlookers and undecideds from the mildde of the Six America's segmentation studies, who may not have focused much on this issue that should be the priority, not the few who are actively and aggressively spreading misinformation. But, as you suggest, the tone we take with the misinformers has a impact on onlookers. All the more reason to remain, as you say, firm and confident rather than dismissive, aggressive or contemptuous when addressing the misinformers. Frankly, I wasn't actually thinking so much of people one encounters on blogs who are a self-selected fraction of the public so much as people encountered face-to-face, individually and in groups. PS Glad the em dash is working in WordPress!
