Okay, okay, now that I have your attention, let me qualify that statement. I like it when providers put it in their profiles that they have an NBA policy.
Personally, I am an equal opportunity hobbyist. However, I recently spent over 2 and a half hours (round trip) driving to see a provider (GFE Phoenix) who apologized politely stating that she does not see AA males. Flabbergasted/frustrated as I was, I left and tried to pull myself off the ceiling as I drove home.
I have since tried to add more clues to my profile that clearly identifies me as AA, but really... should I have to introduce myself each time as AA? Just seems a bit tiring to me. Seems to me that if you are going to place limits, you should clearly identify them.
