I would argue your doctor analogy is flawed in that doctors don't racially discriminate, but biologically discriminate. I guess I can see why you would think that.
> So whether discrimination is bad depends on the context and whats being accomplished.
I agree, but I still haven't seen a good argument for racial discrimination. Can you cite examples of where racism was good for society? I'm willing to keep an open mind about it, but I think in the long run, segregating ourselves is not the right way forward. Maybe this is too disney, but I'd like to live in a world where we can disregard race and reach out to whoever needs it.
