I will never understand why more people don't find this way of looking at life proper: Believe in "God" all you want. Realize that all religious tomes are some of the worlds first social programs, stories written by man that are metaphors and parables to usually help give people guidance and understanding (Job = Never give up tne the face of massive adversity, The Ark/Great flood = Plan ahead and be prepared, etc etc). Just like drugs, people can abuse religion, be weak willed and have others who are usually religious sociopaths control them and turn them into puppets and directly spew their warped interpretation to their "flock". So much so you eventually have the tragedy that we have here.
So I will say again, nothing is wrong with a religious belief, especially one based on kindness , tolerance, and compassion. But when you have gotten to the point where these parents have gotten, you obviously abused religion like some people abuse heroin, and have lost all touch with reality. If you harm your child due to your warped ideas via either inaction or action, you are subject to our laws.
I worship "God" every Sunday...In his church of creation: The wonderful woods where I play paint ball. I breath in the air "God" made, marvel at all the creations and trees and plants "God" made. And pay my respects to "God" and say thank you by enjoying the life "God" gave me.
The term "God" is extremely subjective, and people let their interpretations run wild and create all kinds of dogma associated with "God". To me, "God" is a force, a connective energy between all living (and non living) things. Remember, anything written, was written by man. And mankind will always have an agenda.
