Has a White person been unkind to you? We're generally very friendly, which is why we wave I guess. I understand why you'd take advantage of America's generous H1B policies, so I can't fault you there. You could always self-segregate and live in an Indian neighborhood. It just baffles me that you'd choose to live amongst White people if you consider them hostile. Grizzly bears aren't that dangerous fyi, but I get your analogy. The park ranger doesn't live with or interact with bears, he just exploits their habitat. Anyway - just wave next time.
