FWIW...Some don't care, but some do. I don't think just because an escort is successful or "great" means that he is not a racist. One has nothing to do with the other. I've had the pleasure of being with some great escorts over the years, and I've have had some pretty disgusting comments made to me, because they had no idea what I was. It's amazing what people will say to you when they are unaware of your ethnicity. Top shelf might get you a higher quality experience between the sheets, but it is certainly no guarantee of anything else. As I've gotten older, I realize that minds are rarely, if ever changed, so I don't call them out, unless I decide to pull the plug on a hire. Every situation is different, so there are times when I'll let certain comments slide.
I've always been of the opinion, right or wrong, that you have to chose your battles. Moving the needle on systemic racism embedded into someone's character is unlikely to happen...it is the way of the world. There are too many out there who genuinely don't care, to waste time on the few who do.
