I've got no problem with that. Cemeteries are stupid - dead people are dead, and if anything deserves respect it's their now forever ruined and rotting neural connections in the brain and not their empty husk of a body. Your body is just a sack of shit that's not worth anything, your persona is what matters.
Corpses don't deserve respect. And cemeteries are just wastes of space.
Somewhat more on topic, considering how long it usually takes a body to decay (probably slightly longer if they make an even bigger mockery of circle of life and death and stuff you with preservatives so you look good on your funeral, which is bloody retarded) - it's going to take just a few years for most of your body to decay although your bones will probably stay there.
So most of the bodies in the cemetery will probably be completely deteriorated, and generally 6 feet under and possibly surrounded by pieces of the decaying casket. No fucking dog, especially with it's owner right next to it, is going to dig out 1.5 meters of dirt and earth trying to get to something.
