Ultimately, racism or not, wouldn't any one of us prefer to see someone who feels comfortable with us?
I'm reminded of the old joke about the union rep in Nevada.
He goes to the first brothel and inquires about the financial arrangements. On being told that the house gets 70% and the girl gets 30%, he proclaims that he couldn't possibly use such an unfair service, and turns on his heel and walks.
He goes to the next brothel and inquires, and learns that their arrangement is the same: 70% for the house, 30% for the girl. He's disgusted. He exits and continues down the road.
The next place he enters and asks, he's told (much to his pleasure) that this is a "union" house and the house takes 20% and the girls take 80%. Well! This is more to his liking!!
He looks around the salon and spies a tall, voluptuous blonde. He motions to her and tells the madam, "I'd like her, please." The madam shrugs, "I'm sure you would sir," and then motioning to a toothless 80-year-old woman in the corner, she says, "but Martha here has seniority."
The point is, you can't apply regular rules for racism, sexism. age-ism or any sort of equal opportunity to this business. This is very much a business of preferences -- on both sides. If a client isn't interested in a particular woman, regardless of who else thinks she's the cat's meow, then he's not interested. And if an SP isn't interested in seeing a guy -- over age, race, culture, personality, whatever reason -- then it's best left a no-go.
This is way too personal and intimate a business to expect people on either side to perform under circumstances in which they don't feel comfortable.
