Because, sure, that's what happens:
“I believe that if the Supreme Court, as expected, enshrines gay marriage as a constitutional right, I believe it’s truly going to be, to use your phrase, ‘open season’ on Christians and those who believe in traditional marriage,” Jeffress said. “Once you make gay marriage a civil right then anyone who opposes it is guilty of a civil rights violation.”
Bob Jones University outlawed interracial dating among its students; well, until they lost their federal funding and student loans, grants, etc. They finally gave up and changed their policy, thus giving them renewed access to federal monies. But nobody associated with the university was arrested for a "civil rights violation."
Maybe this is just the difference between being a pastor and being a lawyer.
I remember the story of a church, too, which forced out a lay couple (just members, not clergy or anything) because they were an interracial couple. If I recall correctly, they refused to allow the marriage to take place in their church. Despite Loving v. Virginia, no one arrested the church members or the pastor; the church was just shamed. Whether or not they relented on their racist policy, I don't recall. But again: no one was jailed.
So the "open season" has never come. Which will be good for the rabbits and the ducks.
