To condemn disagreements -- which are an opportunity for discussion -- as something to avoid simply because they might turn out badly is like not wanting to have a pet because you might have to clean up a mess once in a while. The benefits outweigh the costs.
Your eloquence is divine. I bow to you, sir.
I think I can use that pet example with patients. Risk/benefit really gets across with some people. It's what governs most of what I do in the office every day. "Sure, this medicine may make you hungry, but it'll make you functional, too. Try not to eat more than you need and you won't gain weight. If, on the other hand, if you find the Cheetos suddenly irresistable and you gain a few pounds, then hey - at least you've got your life back."
I also agree with CV and the others that, knowing that the Axiom tongue was planted firmly in cheek, the letter was funny. To someone not in on the joke, maybe they'd raise an eyebrow.
No worries here.
