Oh dear, this is one case. I realize it's tragic, but I think it's pertinent to also realize that many other religions have extraordinarily dogmatic custom too...it's just what a certain group of people believe in and I'm fine with that.
There is a religion created solely from Kurt Vonnagut's book,
Cat's Cradle. Now, I'm not entirely familiar with it, but I doubt I would follow the majority of
its customs. It stands more as an analogy than a moot argument in itself...
Simply, just because this is wrong by Western standards/morals does not make it
wrong across the board. Different people have different belief systems, that's all. No need to attack either/or as either/or aren't decidedly correct or entirely wrong (lo and behold the gray areas otherwise known as "social sciences"?).
Thus, I don't know if it's advantageous to really go at the Catholic church (or even Christian faith) for something that a small group of its followers take action in for one particular case.
