Since grammar is becoming more important to you, please note that "all y'all" is a redundancy. Y'all is a contraction of you all. That "all y'all" nonsense was created by a yankee trying to sound knowledgeable. There's you (talking to an individual) and there's y'all (addressing a group). If you wanted to be broadly inclusive for everybody in a particular group, an edit of your comment above would be, "And in case you smoking guys didn't know this...", where smoking guys is "all". Sorry for the OT, but "all y'all" makes me grit my teeth.

I stand by that... But you do realize it was tongue in cheek when paired with the grammar nazism...no?
Though, I will say all y'all is more of a phrase I heard in Atlanta, than here in Texas. 50/50 in New Orleans...ijs
But you're allowed to have any deal breaker you like. And I promise not to use any form of y'all in any of my professional writing in the real world.
