This is terrible and very overly dramatic. This whole "white guilt" thing is getting old. I talk to everyone the same way, and have never had an issue with a conversation strictly because of someones race. White people can be unemployed too, and when you ask someone what they do for a living, its up to them as to where the conversation goes next. I live in South Florida, a cultural melting pot, and have never tailored my conversation to someones ethnicity.

Just treat people how you would expect them to treat you. The rest is up to them, and it's not your fault if they don't treat you how you expect.
