( CNN ) -- Not since that cranky old lady asked `` where 's the beef ? '' has a fast food chain had an ad as funny as the Chick-fil-A cows begging people to `` Eat Mor Chikin . '' And when I moved to Atlanta , where the franchise company is based , I did . Then I found out the company was funneling portions of its proceeds to fight gay rights . Now I 'm back to eating chicken , and not chikin . This is the U. S. Constitution at work -- freedom of speech meets freedom of expression . Chicago 's mayor Rahm Emanuel , Boston 's Thomas Menino and a handful of other mayors threatening to ban Chick-fil-A because of anti-gay marriage remarks made by its president , Dan Cathy ? Not so much . Are you demonstrating at Chick-fil-A this week ? Such a position may sound noble . It may be coming from a good place in the officials ' hearts . But thankfully it is unconstitutional . The last thing anyone , liberal or conservative , should want is local government censoring what a private citizen can say by way of withholding permits and licenses . With the exception of a few examples , such as falsely yelling fire in a crowded space , freedom of speech is n't contingent upon what a person says . So members of the Ku Klux Klan can legally rally and spew hate about black people . Westboro Baptist Church can protest and say terrible things about a soldier during his funeral . And Cathy can say whatever he wants about gay people . That 's the U.S. Constitution at work . You know what else is constitutional ? Rahm and Thomas making out with each other in protest . In response to Cathy 's remarks -- and the fact Chick-Fil-A has donated millions to organizations that fight gay rights -- the Gay & Lesbian Alliance Against Defamation is organizing a same-sex kiss-in to be held at Chick-fil-A restaurants across the country Friday . I 'm not sure if Rahm and the others are free that day , but unlike their talk of banning the franchise , their participation in the lip lock is totally legal . It 's an unconventional protest for sure , one that lends itself to great video , funny interviews and front page stories with women kissing and the word `` chicks '' somewhere in the headline . If you 're thinking of joining in , may I suggest making out before eating a chikin sandwich . Kiss-ins are so much more enjoyable when protesters have fresh breath . Opinion : Chick-fil-A and free speech . Perhaps more entertaining than the kisses will be seeing how Chick 's management handles the situation . Having the CEO ramble on about gay people bringing God 's wrath down upon the nation is a PR nightmare , but it 's manageable . Video of staff kicking people out of its restaurants for being gay -- and let 's face it , if straight people are kissing and get to stay , that 's exactly what it will be -- well , that just opens the franchise up for a more significant financial backlash . Boycotts , like freedom of speech , are constitutional . Perhaps sensing that could be the next step in this debacle , the company recently issued a statement on its Facebook page that read in part , `` The Chick-fil-A culture and service tradition in our restaurants is to treat every person with honor , dignity and respect -- - regardless of their belief , race , creed , sexual orientation or gender . '' This echoes remarks made by Cathy last year when he was asked about the company 's donations to anti-gay groups . Back then he said `` We 're not anti-anybody . Our mission is to create raving fans . '' Well , he 's got people raving , but I do n't think this is what he had in mind . Pittsburgh Mayor Luke Ravenstahl said he `` could not agree more with the mayors in terms of their positions , and I could n't disagree more with Chick-fil-A and their position , and if it 's appropriate for us to take a hard stand and say , 'You 're not welcomed , ' we 'll consider it . '' Again , that 's not necessarily the Constitution at work , but it does sound like another pair of high-profile lips are eligible for Friday 's kiss-in . To be fair , Cathy does have a lot of supporters who are choosing to eat mor chikin . My Take : Chick-fil-A controversy reveals religious liberty under threat . Rick Santorum recently live tweeted during a Chick-fil-A visit , Sarah Palin was photographed this weekend with a bag of chikin and Mike Huckabee declared this upcoming Wednesday as `` Chick-fil-A Appreciation Day . '' This is what the forefathers had in mind when they composed the Constitution : liberals making out during lunch and conservatives stuffing their face with chikin in the name of Jesus . God , I love this country . The opinions expressed in this commentary are solely those of LZ Granderson .
LZ Granderson : I was a Chick-fil-A fan until I heard of its stance on gay rights . Comment: The Constitution does permit people to peacefully protest , he says .
