I disagree with the all or nothing attitude. And I certainly disagree that you are anti-gay, or a closet bigot if you do choose to pay CFA for their chicken and service even with the knowledge of the donations and this interview. Your money does go toward their donations to causes a significant amount of the nation disagree with, though in such vanishingly small amounts that the only thing noteworthy is the principle of the matter. All balanced against their service, quality of food, and other realities of buying from a company.
That's why it's easier for some because they say, "shit sucks anyways, good riddance" while others express some remorse because they enjoyed the food but they cannot support CFA's beliefs whatsoever.
Basically, I believe there's a difference with being cool with eating at CFA even though they are anti-gay "because chicken" as you all so intimately put it, and allowing the convenience, immediacy, quality of service, taste of food, or anything you enjoy about the establishment win out over knowing your purchase contributes less than one-one thousandths of a penny toward a cause you disagree with.
