rgb,
Can you be a little more specific / detailed with what you're saying here? Statements like
I'm not talking about just the difference in accent. I'm talking about extremely poor grammar and disjointed sentences.
sound exactly the same as statements made by people who haven't taken the time to fully study and understand a language. Can you post something that can help the rest of us understand exactly what you're talking about? A technical paper, a reference, a transcript, movie, something?
Thanks!
