Isn't just the language or clothes. People feel inferior/discriminated to eat with their hand (traditional Indian food) as opposed to using forks / knifes, which somehow is supposed to be "civilized". People feel that even when they speak English, their Indian accent is somehow bad / funny. Its not uncommon for people (specially from the western world) to make judgements how Indian/Asian food smells/tastes bad. Wonder how much of these stem from the colonial past of systematically being subjugated and being told you're inferior for 100s of years.
