I don't know where you are from, but I was born in TN. In nearly all parts of the South, grammar is horrendous. It's better among the educated, but overall it's disgusting. It's not relegated just to speech either. You'll see it in print here too. It's just embarrassing to me that people don't take a little pride in their mother tongue is all.
And hey, I love the British accents. There is something very pleasing about them for some reason.
