If it's not criminal, it's not government's business. I'll address these kinds of statements in several ways, because it wouldn't be intellectually honest to ignore them. There are often other solutions to problems that don't involve the thick-fingered grasp of government. Belief system or sexual preference, for instance. At most places that I have been employed, it was generally not a good idea to discuss such things.
Racism is real.
There is no denying it. There are some companies with people in authority that are ignorant enough that they will not consider a white or black or Asian or man or woman for certain jobs. In a world market, that kind of discrimination eventually leads to the company's own misfortune. With modern methods of communication, there are ways to either hurry the death of a company, or motivate them to change their policies. The press is always looking for stories to publish about unfairness in hiring practices.
