Christians blaming the recent shooting on schools not allowing god.

Someone on reddit posted this link and this is seriously horrible.

I am sorry but anyone who agrees to any of the comments/posts made in this link will ignored by me
for the rest of his/her life, and will lose all my respect.

I cannot grasp my head around the fact that people honestly think this way.

This sentence struck to me the most:
''Student: Dear god why do you allow violence in school? God: Dear student, i'm not allowed in school''

To be clear, I have nothing against christians but whenever they start pulling crap like this I get extremely angry.
This is basicly saying.

''Oh well, the guy who shot them couldn't help it. But the school! pineapple them godless piece of crap.''

Discuss?
