> It even means a restaurant should be able to refuse to seat (pick one): black people, white people, males, redheads, left-handed people or introverts. Whatever. They probably won’t stay in business very long, it’s a form of corporate Darwinism.
I think the point of the argument is that you can't pick and choose when discrimination is OK. But then the second half, about corporate Darwinism, is a moral escape hatch, possibly because the author senses how manifestly wrong that argument feels.
There is no one-size-fits-all solution. Right vs. wrong will be a "you know it when you see it" case by case basis. And the test for that will mutate as our society mutates. Things that feel right today will embarrass our children.
What I think is important today is not to rely on capitalist mechanisms to protect minorities from discrimination. Wheelchair ramps are needed by a tiny fraction of our society. Many businesses probably wouldn't bother with accessibility, but it's mandated, because the disabled don't have a large enough wallet to bankrupt companies that don't put ramps in.
