Apparently, even after more than 50 years, some people do not understand the basics of the 1964 Omnibus Civil Rights Act, whose guiding principle is that if you open to do business with the public, you are a public accommodation, and you cannot refuse to do business with people on the basis of race, gender or sex, religion, color or ethnic origin.  This Masterpiece Cakeshop case is essentially no different from a diner refusing to serve a black person.  I am sure that in the 1950s and 60s, many of the diner owners believed that God wanted them to keep the races apart.  But that issue has been settled.  There is nothing different here.
