Well, sure, but that's on them. The belief that a counselor will not be able to help you, for whatever reason, will generally be a self-fulfilling prophecy. I see no salient difference between a black person deciding that a white person can't help them because they are white, and a white person deciding that a black person can't help them because they are black. To me, both of those positions are equally odious. One thing I've learned first-hand over the years is that you can't help someone who won't help themselves.
