Ah, the irony. They do not boycott CFA because of its tortuous treatment of chickens before slaughtering them. And not because CFA makes Americans fat by deep-frying that chicken and serving it on white bread. It's because CFA is not discriminatory enough. CFA should be Christian without being Inclusive; the two are obviously incompatible.
It recalls the line from Life of Bryan: "what Jesus blatantly fails to appreciate is that it is the meek that are the problem."
Anyway, Raising Cane's is much better.
