Once upon a time there were lots of eateries in the south that openly advertised that they were "Whites Only." Now, even if it weren't for the laws, societal opinion would strongly castigate such behavior. The same will be true for this bigotry. Someday the grandchildren of the hoards that drove to the chick-fil-a appreciation day will be ashamed of their grandparents.
Time is not on the side of bigotry.
