Appreciated. For what little it's worth, I'm not assuming any malice out of you, I'd like to think this is a pretty good-faith conversation here.
I'm making a choice not to read maliciously into this, because it's not a great choice of words or argument, and in a lot of cases can be construed as misleading in an emotionally manipulative way. I'm sure you don't mean it that way, but let me explain.
African Americans, I would wager in lack of evidence to the contrary, are not employed at any significantly higher rate by Papa John's than they are by Pizza Hut or Domino's or Little Caesar's. Thus, choosing specifically to give money to Papa John's isn't really any greater expression of "support" for the local economy or African Americans than if you had ordered from any other pizza chain. I mean, I'll grant that it's true that your money does not end up solely in John Schnatter's pocket, but the money that goes where you do want it to is not really that different no matter where you get your pizza.
Now, despite all this, it's totally your right to spend money at Papa John's. I absolutely understand the difference between doing so in explicit support of Schnatter's views and doing so out of simple comfort. However, buying pizza from Papa John's knowing full well that some of your money goes to John Schnatter and the positions he uses his political and financial power to push... well, if you do so out of mere comfort when alternatives are readily available, I'm going to be disappointed in you. Not spiteful, not outrage, not mocking, disappointed.
And my money is where my mouth is on that, I've confronted my own long-term romantic partner about her being a bisexual woman and still giving money to Chick-fil-A, Hobby Lobby, and Kentucky Farm Bureau (an insurance company that similarly weilds its political power in opposition to LGBT people). So at least understand that I'm not some loon preaching at strangers, I have had those uncomfortable conversations with people I love. That's what this means to me, and many people like me.
