individuals maybe, but large organizations that people depend on no. and even as individuals we need to be careful to not allow prejudice to control our actions. some people take "being black" as a red flag.
it does negate people are free to have red flags that cause them to cut ties with other people because you are not free to have whatever red flags you want. if you see red flags you should evaluate them and make sure they are not just prejudice.
remember that joke about a someone in an airplane sitting next to a black person, complaining loudly that they want to sit somewhere else. the stewardess comes over and says: "my apologies, it is of course unacceptable that you should have to sit next to such an obnoxious person". and then invites the black person into first class to everyones applause.
you can leave, but if you complain you should probably be kicked out.
i don't know why we are having such a stupid argument. it should be clear that racism is unacceptable and that it doesn't give you any right to show disrespect.
