Technically speaking, neither does digging up my ancestors' bones, using them in bizarre satanic rituals, and then peeing on them to extinguish the flames ... but I really wouldn't appreciate anybody doing that out of simple respect for my forefathers, if nothing else.
Disturbing a grave is a crime.
Do you wish to make pretending to baptize someone a crime as well?
Otherwise, there is a difference between physically disturbing someone's remains and merely using their name in an empty ceremony.
