Appearing this week on FRC's Washington Watch radio show, Austin Nimocks of the Christian conservative legal group Alliance Defending Freedom (ADF) warned that gay marriage foes may soon be “put in jail.”

The ADF is currently representing Barronelle Stutzman, owner of Arlene's Flowers, who last year refused to supply flowers for a gay couple's wedding. The state of Washington asserts that in denying the couple service Stutzman violated the state's Consumer Protection Act.

“When it comes to running a business you cannot discriminate against someone based on their religion, based on their race, based on their age, or in this case, based on their sexual orientation,” said state Attorney General Bob Ferguson. “And unfortunately, that's what [Stutzman] did here.”

“[T]he persecution,” Nimocks told guest host Josh Duggar, “is only going to ramp up and it's going to become more fierce.”

“We appreciate so many of those who are willing to stand for marriage in the face of brutal opposition and public excoriation,” Nimocks added. “I don’t think we're far away from a day where we might see somebody being persecuted to the point of being put in jail for standing for marriage.”

The state's lawsuit seeks fines against the business, while a second suit seeks damages on behalf of the gay couple.
