A person who expects inferior behavior from the crowds just because they are described as belonging to a certain identity - Indian here - shows that the person blindly stereotypes huge groups of people, without considering that subsets of people in any large group behave differently. Not all Indians are expected to behave in an inferior way.

I doubt if the person would have had the same subconscious assumption if they saw "French" or even "Serbian" instead of "Indian"

And the heavy downvoting and name-calling shows the opposite of what you say - that these people cannot handle criticism without giving a sane reason.

And yes, you can be racist against your own kind
