It's Mike Huckabee's idea, and it's a nice "in your face" slap back at the righteous liberals who proclaim their love of the 1st Amendment and then undercut the notion of freedom of speech and religion by punishing anyone who doesn't believe as they do.

NBC News:

Supporters of restaurant chain Chick-fil-A, which has come under fire for its president's anti-same-sex marriage stance, are planning a "Chick-fil-A Appreciation Day" on Wednesday.

According to news reports, Christian conservatives have promised to buy the Atlanta-based chain's waffle fries and chicken sandwiches to show their support of  President Dan Cathy, who recently told a Baptist publication that he was "guilty as charged" in his support of the "biblical definition" of the family as being between a man and a woman.

The statement sparked a firestorm of criticism from gay marriage supporters and politicians, turning Chick-fil-A into a lightening rod for the debate over same-sex unions.

Former Arkansas Gov. Mike Huckabee, a Baptist minister, declared Wednesday "Chick-fil-A Appreciation Day" to support a business "whose executives are willing to take a stand for the Godly values." Former Pennsylvania Sen. Rick Santorum, who like Huckabee ran for president as a darling of social conservatives, joined the cause along with religious leaders.

"As the son of a dairy farmer who milked many a cow, I plan to 'Eat Mor Chikin' and show my support by visiting Chick-fil-A next Wednesday," the Rev. Billy Graham said in a statement last week, referring to the slogan in the company's ads, which feature cows urging people to eat poultry. 

People on the other side of the debate are planning to have same-sex kiss-in at some restaurant locations on Friday.

Many may be unaware that the chain puts its money where its mouth is. Chick-fil-a is one of the only large companies in the US that is still closed on Sunday to honor the commandment. A $4 billion company that forgoes profit by being closed 1/7 of a week is to be admired for possessing values and sticking with them regardless of the cost.

So there's more to appreciate about Chick-fil-a than the personal stand of the CEO, maintained under the most vile and despicable criticisms.
