Look, I agree. I shouldn't be forced to do something for someone who makes me uncomfortable, even if it's something that they can't change, and which doesn't materially impact me in any way.

But at the same time, do you not see how this reinforces existing disparities in opportunity and social acceptance? If you have a better solution than mandating that businesses don't discriminate, I'm all ears. However, if you simply allow businesses to freely discriminate, then the world will only become more unfair over time.
