Problems in English Variations!

In my last posts I've expressed that I think that language variations aren't bad, because they keep the culture of the speaker alive. However, speaking English in a different way may cause some problems. A clear example is Gloria, from modern family, a series that shows how this woman has problems communicating with others because she doesn't pronounce correctly.

I think that native speakers easily identify a person who talks English with miss pronunciation, and this could create a great variety of social problems, because there is a tendency to make fun of people who is doesn't speak English correctly. However, I think people may feel proud of speaking English with some changes from their native language. Also, I think this is not a inferior variation of English, and the problems that it may produce are sadly because people may think some countries are inferior to others, so the way you talk just helps others identify your origin.

For example, while being in the Scots College in New Zealand, we have a Physics teacher that was from India. He clearly talked English as he would in India,   pronouncing the sound "r" really hard (for example in the word "Current"), and repeating the word "right" over and over again. However, student's could understand what he was saying and he could communicate what he wanted without major problems.
