Perhaps you missed the part where I said there was exceptions to this rule.
Outside of that exception, it is racism.
Not an extreme take at all, reality can be blunt and harsh and isn't sugar-coated at times. Every reason provided will come down to that. You can say it's reductive all you'd like, it's not. This is fact, this is clearly discussed amongst providers many, many times as well.
I welcome you to provide an example of a reason that doesn’t come down to perpetuating stereotypes if you disagree(outside of the exception).
Again, everyone is welcome to their preferences, that doesn't mean their preferences can't be called out.
I have a really hard time believing that we will be having a discussion in good faith when you say "Every reason provided will come down to that". This signals to me that your mind is already 100% made up that any examples or alternatives provided will be reduced to racism in your view.
The "exceptions" you provided is that black girls may have private reasons for not wanting to see black men. That's not very clear but I assume you mean they don't want to meet other black men they know. But escorts of any other race does not appear to be doing this?
I think personal taste/preference is something that is hard to really describe - For example I prefer ladies of a certain color, and I am not actively seeking to meet with women of other colors simply because of my tastes, experiences, etc. I think you're going to label this as racism and descimination - and I think you'd be wrong.
The size/stamina thing has been mentioned also - This could likely also be a contributing factor as well.
Some ladies do not have a 50/50 clientele of black men like you do and may have had a small sample size of black men and they did not enjoy their company, or as I alluded to in a previous comment in this thread they had a bad experience. I won't be naming names obviously, but I've seen an escort where the topic came up that she had a bad encounter where she was robbed and hurt (no details of how badly) and that she had decided not to see black men based off that encounter. Again, I think you're going to reduce this to racism and descrimination instead of understanding nuance but these are some examples.
I want to add that if ever I saw an ad that singled me out in any way - Age, race, size - whatever - I'd just continue on with my life and understand that escorting is a little bit more nuanced than a regular job and that there is a level of chemistry/personal preference that plays into the decision being made to see a client.
Thats my 2 cents.
