I don't think that's what he's saying, KC. He's trying to tell you, albeit not-too-gently, that traditionally the onus is upon the listener or reader to look up words or ask the speaker what that means. It's a way of punching up, as it were, and it 's a pretty standard way to look at it. The onus is on the unlearned, not the learned. The learned have every right to use words that better fit a situation than a standard one. It's not to get at you or make you feel inadequate. It's to dance with language for a bit.
In addition, I don't know what debates came before, but I'd post what you want and then let the other people tell you by deed what flies here. It's been a while since you've been here, and I can't remember you ever really getting it. Maybe it's time for a new board, or a new approach. I know I at least found a few friends with my personality here when I changed both approach and temperament.
Anyway, I'm giving what I hope to be helpful advice. You seem like you're pouting a bit, and that's no way to make friends. Peace, man, rock
