And that has been the age old argument. Yes, escorts sell companionship as their service but if they want to be treated like a legitimate business, they need to act like it. If there is some large section of the population that they cannot serve for personal reasons, like a certain race, overweight indviduals, or elderly individuals, then they need to reevaluate whether they are a business or something else entirely.
As for businesses that discriminate, I think public opinion is showing that it is not to be tolerated. Just observe the recent firestorm with Abercrombie & Fitch and that woman baker who refused to make a wedding cake for a gay couple. In my opinion, and it is my own, escorts who refuse a certain segment of a population based on their personal prejudice(s), are in the same category as those examples.
