There is wisdom in your words. I can, however, understand the sense of being put upon by the claimants. A great deal of their frustration and anger is generated by their youth and lack of life experience. When I was young, I would become angry by being summarily dismissed because I'm black, but aging and life experience made me understand that "I am what I am" and that I like what I am.
I have a different perception of preference. I don't perceive it as a myth or a limitation. When I was young and active my preference was for Asian hotties (Chinese, Japanese, Korean, Filipino, etc.), but it was a preference, not a requirement. I was also chasing the Spanish hotties. And, this will give you a chuckle, I just gave up on the black hotties...not because of any racial considerations...the ones that got my attention were tops and just too big. I must have been in the wrong line at the penis bar.
