Yeah he was just trying to point out the improper spelling of it. I am from the South too and I've seen it spelled both ways. I will also point out that this is why we're mocked. It doesn't make sense to take pride in improper grammar and it would benefit our children for them to know the difference regardless of how they choose to spell it. It still sounds the same no matter how you spell it and leaving generations ill-informed on proper conjunctions doesn't help them in any way.

I think that's why it matters to point it out. God bless.
