I think it extends beyond Indian folks. I once worked at a company where, Manufacturing engineers were overwhelmingly Vietnamese. Safety staff was Chinese, Engineering was mostly white, and the machine shop was entirely Hispanic. In each case the manager of the department was of the aforementioned race.

There was also a son of a bitch who was an aggressive baptist. He though I was a baptist because I had dated a baptist once, and knew some of the lingo. I really liked him until I saw him treat a Chinese person like crap for no reason. He treated anyone who wasn't a Christian like garbage.v
