If you're talking about government officials (e.g., county clerks, justices of the peace), you're probably right. If you're talking about churches, you're wrong-- no one in the US has ever successfully sued a Catholic church for not performing a wedding where one of the spouses is divorced, and no one has ever sued an Orthodox Rabbi for not performing an interfaith wedding.
And you are not listening. I said, a church CANNOT turn down a couple to be married, based on skin color, and I daresay that said church would be sued and regulated into oblivion if they did. Now, this SCOTUS opinion in favor of deviant marriage has placed deviant sexual behavior on the SAME LEVEL as race - both are now "civil rights". Therefore, a church that turns down a deviant couple based on their deviant behavior, said church can now be sued and regulated into oblivion.
