Out tennis legend Billie Jean King has weighed in on the controversy surrounding Kentucky clerk Kim Davis.

Davis, the elected clerk of Rowan County, was freed from jail on Tuesday after serving five days for refusing to comply with a federal judge's ruling ordering her to issue marriage licenses to all qualified couples. Davis, an Apostolic Christian, has said that issuing marriage licenses to gay and lesbian couples would be a violation of her conscience.

Yahoo! News anchor Katie Couric asked King her thoughts on Davis.

“When I see that, I think of lack of understanding, the unknown. It's always a fear factor,” King said. “And that every one of us is God's children. You've got to have tolerance and I find that they live in fear of others, the unknown. If you're not just like them, then you're no good.”

“I don't know how much time they've spent with somebody who's gay.”

“What's important in the way the world is moving is inclusion and more diversity,” she added.
