Take a knee: I don't expect this to register with you, but sometimes, the only "right" way to respond to a post like Scott's does not involve giving your opinion or advice, no matter how well-informed you may or may not be.
In other words, I don't care if you're the medical director of Sloan-Kettering, don't be an ass-hole.
So, if I shout at someone about to step in front of a bus, I'm an azzhole? I'd readily agree that sutlety ain't my strong suit, and maybe I am an azzhole. It is what it is.
