<I think the difference, is that English originated in England, and some of the native speakers were exported to the US, Canada, Australia, and New Zealand.>
When were native speakers exported to the US? The US became the US at what date?
<The situation in India is about the same as that in France. The French learn English at school, and/or from their parents. >
Was France ruled by Britain for a few hundred years?
<Now, we could certainly call this a "dialect", and even a "standardized dialect" of English-->
As is Standard American English.
<Over here, I'd say that the majority of people don't even know that many people speak English in India,>
May Americans would not eveb know that Denmark is a country. So, time to educate yourselves?
<most people I've talked to have rated it far below say a strong Chinese, or Vietnamese accent in comprehension. >
How many people would that be?
<Remember, that we have a different mentality over here, since we are not often exposed to people with a strong accent. >
Not even Spanish speakers? I think what is really happening here is that you and your mates don't have much contact with "foreigners" who live in your country.
I've been teaching EFL for 26 years all over the globe. Most of the studtent complaints I get about understandability are related to the way white Americans speak.
