What also makes me uncomfortable is seeing something as retarded as "religious objections" as a growing reason for not doing an autopsy. In the Middle Ages, scientists had to buy bodies illegally to make their studies, risking to be burned at the stake for that "horrible crime". Haven't people learned anything yet? What the fuck does their god of choice care if someone cuts open a dead body? He refuses to welcome the deceased guy in Heaven, or Valhalla or whatever?
Western civilization has a notion called "religious freedom". We've discovered that things are much more peaceful if we ensure that everyone can practice as they see fit, regardless of how wrong we their religious beliefs (or lack thereof) may be. (Exceptions to the above when said practices involve harm to others.) So if my religion doesn't allow for routine autopsies, for whatever reason that you clearly don't understand, how about leaving it alone? You may feel free to instruct your heirs to handle your remains as you see fit, and the rest of us might appreciate the same courtesy in return.
