Aaron and Melissa Klein own and operate Sweet Cakes by Melissa. In the past few months, they've faced heated scrutiny - some in the form of physical threats - from those in the gay-rights crowd who decried their May refusal to bake for a lesbian couple who wanted to marry.

The Kleins cited their Christian beliefs of traditional marriage when they turned down that business gig, The Blaze reported. But the lesbian couple filed a complaint with the state, accusing the shop owners of discrimination.

Since, they've been hounded by vicious telephone calls and emails.

Some of those threats were shocking. One emailer wished for the couple's children to fall ill. Another expressed hope that Mr. Klein should be shot and even raped, The Blaze reported.

And yet another wrote: "Here's hoping you go out of business, you bigot."

The couple said on top of that, their vendors were "badgered and harassed" into stopping all associations with the bakery.

The Kleins say they're now closing up their doors and moving their operations to their home. Their business, they say, has suffered a serious revenue hit from the unexpected activism and backlash.
