Two quotes to think about:
Tyson: Being an educator is not only getting the truth right but there's gotta be an act of persuasion in there as well. Persuasion isn't always here are the facts and you're either an idiot or you're not. It's here are the facts and here's a sensitivity to your state of mind and it's the facts plus the sensitivity when convolved together creates impact.
Dawkins: Just one anecdote to show that I'm not the worst in this thing. A former and highly successful editor of New Scientist magazine, who actually built up New Scientist to great new heights, was asked "what is your philosophy at New Scientist?" and he said "Our philosophy at New Scientist is this: science is interesting and if you don't agree you can f#@k off."
