With that kind of reasoning, abortion is okay because infants would die sooner or later (old age if nothing else). And if the Cathars weren't Christian, it was by Catholic standards. They considered themselves Christian but it was a mixture of mysticisms and Scripture. But yeah, if they weren't Catholic, I guess it's open season on Cathars.
If you want to claim the Cathars as Protestants, be my guest. It says more about your own belief system than anything else.
Wow great use the logical fallacy of Reductio ad absurdum /SARC
