Why, because you don't know what it means? Y'all is a contraction of "you all" and is a Southern colloquialism. Some people think they are being attacked personally when the pronoun "you" is used, even when it is meant for a group and they complain to the RM. If you think this is speaking to you, then listen.
Why do you send this message trying to put all Catholics in one bucket?
Were you pinged, Sal? I'd say "y'all" applies to those who do what I said they do. Do you ever do those things?
Will let you hang on to your southern slang then. I always thought you were an American.
