But they are more than happy to blame God when a nut case gets angry at his mom and kills her and her entire class of kids.
There's a side of me that agrees with you. God, if he exists, certainly doesn't hold our hands. That said when something like this goes down, it really can't be blamed on God.
There's a flipside to that coin though too. That if God does exist, and if he's as all powerful, loving, concerned, etc. as his adoring worshipers would have you believe, you'd think he'd be more prone to making his presense felt and have a greater hand in the affairs of this planet.
