Agnostic here. I don't see the issue with religious people or their products as long as I'm not directly being preached at as a precondition of partaking in their services (Fuck you, Salvation Army) or that there's not a subtext for hating others in the community.

And the glorifying god thing? Bach wrote his music soli deo gloria ("Glory to god alone), but that doesn't mean it has no value to me. I'm not saying these guys are the Bach's of donuts, but I'll wait until I taste them to decide if it's worth another trip.
