when it would affect the circumstances of the decision. If I was hiring staff for my veterinary office, should I employ someone who cannot communicate clearly with my customers? If my office was in a predominately white town in the midwest and I hired a front desk staff member who spoke Ebonics, I would totally put off any client who walked in that door. Even if they understood him, they would likely have such a chore of it, I just might have them walk back out again. However if I knew the area my clinic was in had a great deal of Ebonics speakers, it might be a better idea to hire him! But even that is discrimination.

Language isn't just part of someones identity. Yes, it is wrong to call someone an idiot because they speak spanish...but how they speak also directly affects how effectively they communicate in a given situation. Just like you would not want a surgeon with cerebral palsy operating on your body, you would not want someone with unintelligible communication running your customer service desk. If you're going to consider Ebonics a legitimate "language", then you're going to have to accept that it is grounds for some discrimination...just like people who only speak Spanish.
