As I tried to make clear, while I can't help what I notice, I don't much care either. However regardless of how little you or I care, there are many situations in which it makes a difference.

Regarding the future, current economic trends do suggest that Indian versions of English will become important. However they are not important now. Similarly if you're seeking to make a professional impression you don't want to use slang that is associated with any particular region or ethnic group. For example I would avoid saying "mensch" in a formal presentation.
And for the record, you are succeeding in using English well despite the fact that you're complaining about the impossibility of doing so.
