...so they have a hatred for crackers then?
If they had a hatred of crackers, they would go to a mass(says that's how they got it). Wait all the way through the end of the mass. Process up the aisle to a priest that says an oath. Take the host from the Priest and pretend to eat the host or pretend it is for a sick relative that couldn't go to mass. Then go home and burn it. I doubt their hatred is for crackers they could of gone to the nearest convenience store.
