I bet in reality, you have no clue. You just assumed. You had to turn down tons of good competent white women. It has happened several times to myself and my friends, as well. This gentlemen was African American, in case you hadn't guessed on your own.
Some brothers be like that sometimes.
I hope you don't indict the entire black race based on your experience with one drunk fool at a bar. If you admit it, so do you. For years, being white was an extra advantage. Now that its not, folks like you are getting pissed. Personally, I don't blame you.
