It is hard to know how to react to this.
First of all, it's a waste of perfectly good bacon.
Second, it is, as my Duke colleague D. Schanzer notes, "intolerance." (He also says that intolerance is in "plentiful abundance," which must be different from regular abundance, I guess...)
I can see that someone might think it was funny (in a not very funny, drunk redneck yelling "FREE BIRD!!!!" kind of way). But I can also see, and moreso, how an already beleaguered minority would perceive this as a threat. If you want to have ham on Easter, to show you are not Muslim (or Jewish), then go for it. But why do you have to go defile someone else's church?
The KKK does not represent mainstream Christianity. Al Qaeda does not represent mainstream Islam. Lay off other peoples' churches.
