Catholics are NOT tied in with Protestants and Catholicism is a religion on Her own. All the Protestants in the world combined do not amount up to all the Catholics in the world not even close. Not even half. There are 32,000 different Protestant religions according to the Oxford Dictionary.
I heard that 60% of Americans would not want to be kept alive if in a vegatative state like Terri Schaivo. But that still doesn't make it right. It's not a democratic vote. If 99% would want death, it would still be wrong. And now for the fanalie:
Even if ALL people would want to die, it would STILL be wrong. Because what God says it right and what morality says is right is right is right is right. Forever.
