Though I know it has been pointed out countless times before, let me attempt to make it clear once more.
No one here thinks you are a bigot for, as you put it, railing against quota systems. For that, you are merely ignorant of how affirmative action programs actually work.
The reason that the whole black surgeon thing has gotten you the label of bigot 'round these parts is that it highlights the fact you assume, based on nothing other than skin color, that black surgeons are more likely to have gotten where they are based on affirmative action, and therefore less likely to have done so based on academic merit, than anyone else who wasn't black. Your su ion, based upon your own words, does not apply to Asian surgeons, female surgeons, or any other variety of med student who may have gotten a leg up thanks to quotas. Nor does it apply to rich white male surgeons who may have gotten through med school thanks to Daddy's money.
Again, unfounded su ion alone does not make you a bigot. It makes you paranoid. However, when your unfounded su ion applies only to members of a certain race, based solely on the color of their skin, well... welcome to bigot-town.
