I am a Caucasian person, as they define it. What I have been putting down on various forms under "race" for almost 40 years is "human," because scientifically and morally, that is what we all are. Making judgment solely on the basis of skin color is about as stupid as discriminating against people because they are left handed, have green eyes, or prefer strawberry ice cream to chocolate (deluded as those who prefer strawberry are, don't get me wrong).
Jeffrey Dahlmer was white, so is Charlie Manson, and a whole bunch of serial killers who have murdered sex workers. It is one thing not to see a particular person because of their behavior or negative information you have about them from a reliable source. It is another to judge and exclude a person automatically on the basis of skin color. I don't want to live in a world where that happens.
I have therefore, in the past, declined to make appointments with providers who openly state that they absolutely refuse to see African-American men (or those of other races, but exclusion of African-Americans seems to happen most often).
I can't control what anyone else, provider or hobbiest, chooses to do individually, but I do have control over my own behavior, and if a provider excludes all of my African-American, Hispanic, Arab, Asian, or Native American brothers, they can exclude me too.
I'm a landlord of a small building, and I've rented to African-American families, interracial families, and people of a variety of races. The worst tenant I ever had was a white DePaul graduate student (you really don't want to hear the details, but it would make for a frightening screenplay). Yet everytime I rent to African-Americans, I've gotten bullshit from bigoted neighbors, who make it cloear that they don't approve, make harassing calls, etc.
I am sick of racist bigotry.
