And thus "progress" comes full circle. In Minneapolis last year, the airport licensing authority, faced with a mainly Muslim crew of cab drivers refusing to carry the blind, persons with six-packs of Bud, slatternly women, etc, proposed instituting two types of taxis with differently colored lights, one of which would indicate the driver was prepared to carry members of identity groups that offend Islam. Forty years ago, advocating separate drinking fountains made you a racist. Today, advocating separate taxi cabs or separate swimming sessions makes you a multiculturalist.
