This still doesn't make it a dialect though :) Sorry, but it just annoys me to see American English fanatics say how British English is "wrong", or a "dialect" of American English when it was the original base of American English to start with :)

I do agree with you, languages evolve. But that doesn't mean we should just drop grammar altogether. I was a little snappy in my original response, and I apologise for that, but the sentiment is still the same.
