I'm sorry that you have witnessed mistreatment against Indians by non-Indians in the past, but that does not give you the right to baselessly slander the reputation of a stranger because you personally misinterpreted what they said.
You don't know anything about the original poster; he could be Indian (or have partial Indian ancestry) for all you know. He might have been the leader of a campaign for equal treatment of off-shore development workers. You don't know him, and here you are accusing him of racism because you witnessed some other people being racist to Indians in the past. I don't know what else I could say to you to explain why this is wrong, so I'll just stop here.
I regularly work with Indians, and have plenty of Indian friends, and co-incidentally love Indian food. Race did not even enter my mind upon writing my original comment.
