That's a fair point, but I'd argue that gender differences and racial differences are, well, different. There really are salient
biological differences between males and females, whereas the differences between blacks and whites, while real, are purely social constructs. If you judge a prospective counselor by the color of their skin you are IMHO part of the problem.
This is not to say that you shouldn't judge a counselor by their behavior after you've started working with them. But I think it's possible for a person with black skin to be just as insensitive to the concerns of black people as someone with white skin, e.g. Clarence Thomas.
