Then why the topic question at all?
To create faux outrage.
Public Accomodation laws specifically exempt houses of worship- so from the beginning it was a false thread.
Beyond that, churches have always had the authority to discriminate as the church wishes to- the Catholic Church doesn't allow women priests, the LDS for years treated African Americans as a different level of membership within the church- all perfectly legal.
No one will ever force a church to marry anyone the church doesn't want to.
