Also, it would be trivial to use this brand of multiculturalism to justify open racism. Why should a Chinese person in Chinatown who doesn't speak English allow a white family to stay in their property? Or allowing a Russian to deny a Ukranian? Or allowing a black family who have been victimized by the police to allow a family containing police officers.
I imagine most SJW's would agree for "special exemptions" for these cases. The idea that no one should be turned down is asinine. These are people's homes and by the 4th Amendment the government can't shove people in them. Want to stay somewhere where they don't have these issues? Then call a hotel.
