Here is the problem with the whole Chick Fil-A business: it is a cop-out. I don't want to get into the sociopolitical aspects of the thing (leave that to the politicians to argue about), but I do think the church has something to say about all this, though it might not be quite what you think.
Let me first offer two complicating factors. The first is that, in our usual modern way, the whole conversation about Chick Fil-A is much more complicated than we are admitting. Questions about business and ethics are rarely clear, which is part of the reason "business ethics" sometimes seems like a paradox (it is also the reason, I think, the recent financial crisis ended up being so difficult to diagnose. Business is complicated). Chick Fil-A is a francise business, and it is certainly the case that not everybody who relies upon Chick Fil-A for livelihood shares Dan Cathy's opinion on gay marriage.
The second complicating factor is that as far as I can tell, the conversation about Chick Fil-A is not about traditional vs. gay marriage as much as the media is making it out to be. I do not care what the owner of the restaraunt at which I buy my lunch thinks about marriage equality; there are no gay chicken sandwiches. The conversation, at least as far as I find myself interested, is that profits from Chick Fil-A have been sent to Exodus International, a group that does much more than oppose gay marriage. Further complicating is that only a very small portion of the money spent on behalf of Chick Fil-A went to Exodus International as compared to the overall spending of the Winshape Foundation, the Cathys' charity. Even so, and this is just me talking, any amount of money spent on so-called "reparative therapy" is troubling, for these methods have been largely discredited and can, in fact, breed "prejudice and discrimination."
But neither of these complicating factors are the real issue. They are smoke screens for the real issue, for the issue is this: rather than confronting the issues at hand (homosexuality, the nature of the relationship betwen business and church, the way in which we treat our enemies), we are transferring our anger to a fast-food chain. Rather than working this out in the church, we have transferred our own responsibility to a chicken sandwich chain, as if the way in which we are called to live our faith is expressed most clearly in our fast food preferences. Those in favor of marriage equality have decided to boycott Chick Fil-A. Those opposed have decided to buy extra fast food on August 1, Chick Fil-A Appreciation Day.
I am not in the habit of speaking for God, but I have great trouble believing that God cares all that much about where you eat lunch. I don't think that the best way to show your support for an issue is to buy fast food.
Now, issues matter. I feel passionately about this particular issue, so I have found myself, at times, swept up in the hype. And as far as the Chick Fil-A issue is related to matters of personal integrity, it is an intereting exercise. Should you support companies that take public stances with which you disagree? How can you be a person of faith in a complicated world? These are important things to think through.
But the conversation is not about integrity: it is about Chick Fil-A. The conversation ought to be about the issue itself, not about Chick Fil-A. The problem is that it is WAY easier to get steamed about fried chicken than it is to work to advance an issue. It is much easier to complain about someone's money than it is to involve your own. I wonder how many people--on both sides of this issue--who have taken public stances on Chick Fil-A have put any of their money where their mouths are.
It is true: talk is cheap. Working to advance the Kindom of God is difficult (and, in fact, expensive).
Support marriage equality? Fine. Work for it. Spend your time and money advancing the issue. Forgoing a chicken sandwich is fine, but it is hardly a sacrifice befitting Christ, our Lord.
Disagree with gay marriage? All right. Work for it. Go buy a #1 if you want, but don't pretend you're doing church. Church is something else entirely.
