This assumes that the business differential exists and is large enough to matter.

I generally point out the lack of non-smoking bars/nightclubs before all the anti-smoking laws went on the books. Everybody agreed that non-smoking venues were a good thing, but non-smoking bars/nightclubs simply did not exist because the business differential was too high (smokers were so much more profitable than non-smokers that even though non-smokers outnumbered them nothing would cater to the non-smokers).

In the case of AirBnB, how much profit will someone give up by not serving <ethnic group>? Not much since most of these places are just getting a little bit of profit for renting out extra space.
