An Indiana pizzeria under fire for saying it would refuse to cater a gay wedding shut down on Wednesday after its owners said they received threatening messages. However, a GoFundMe page set up for Memories Pizza in Walkerton has raised more than $40,000 in just six hours. The pizzeria made national headlines this week when its owners called the business a "Christian establishment" and said the state's contentious Religious Freedom Restoration Act would allow it to refuse to make pizzas for a hypothetical gay wedding. That led to a flood of angry reviews on Yelp as well as the threatening messages. “I don’t know if we will re-open, or if we can, if it’s safe to re-open,” co-owner Crystal O’Connor told TheBlaze, the news network run by conservative talk show host Glenn Beck.
