Is it ever right to use a racial slur to make a point?

[Ravenshire]

Never gonna happen. The best you can hope for is that skin colour is treated the same way as hair colour, or eye colour. We'll never get to a point where people's defining features will be ignored outright.

When "the black woman sitting at the front desk" becomes the same type of descriptive language that "the brunette woman sitting at the front desk" is today, and carries the same emotional temperature gradient, it will be a great day for humanity.
