[[yet as long as it is a private entity, then I think they can enforce dress codes]]
IF Sweetcakes isn’t considered private, and they must bake a cake for gays, then a mall isn’t private and they must not be allowed to discriminate against someone’s religion
Bake The Cake Mall of America!
Sadly, the problem is that SCOTUS has confused a "orientation" and behavior-based identity with such amoral aspects as color, race, ethnicity, national origin. Thus just as a store can tell a veteran with a flag on his hate or a Trump supporter to leave, but cannot do so on the basis of color or ethnicity etc. - and sexual orientation - so also Sweetcakes, Masterpiece, etc. could refuse to create a cake celebrating divorce or a political event, but cannot refuse any service, no matter how customized, on the basis of race etc. or sexual orientation.
The SCOTUS ruling legalizing homosexual marriage, thus effectively criminalizing failure to recognize it, is a result of the Christian spiritual decline of America, and failure of the Founders to make it clearer that since the state cannot but affirm one ideology over another, and that this flows from religion, and that it was the general Christian faith that characterized America, then its basic moral tenets where to be definitive in controversy, without creating an official state church.
