While bacon-mania certainly has some corporate/big-farm backing, and at least a small amount of being a pushback (like some pro-steak sentiments) to being demonised by some for your choice of food preference, I find it more than a bit of a stretch to suggest there is any antireligion thing going on aside from those few for who everything is a chance to be anti-[insert-religion-or-other-thing-here] that they jump at enthusiastically.
