The Dignity of Gay marriages was part of SCOTUS decision: Will that bring about "dignity codes" which are against the First Amendment?

A George Washington University professor says "perhaps."

George Washington University law professor Jonathan Turley says the opinion recognizing the dignity of gay marriage could pave the way for dignity codes that trump free-speech rights.
Turley says “the most direct way” the majority could have upheld a right to gay marriage in Obergefell v. Hodges would be to find that sexual orientation is a protected class under the 14th Amendment’s equal protection clause. That would have made a refusal to issue gay-marriage licenses illegal discrimination, and would have clarified the standard in areas such as employment discrimination and refusal of public accommodations, Turley says.
