"You can't discriminate based on race - that limits choice but who would support the contrary?"

If someone refuses to serve or otherwise interact with me on account of my race, I would not use the threat of deadly force to change his behavior, nor would I advocate that anyone else do that on my behalf.

That is not to say that I approve of racial discrimination, or that I would do absolutely nothing about it. I am only stating what I would not do about it.
