What we seem to be arguing is the question of "Do we blame the man or the gun?"

To me, blaming a gun for a man's death is illogical. Blaming the man that pulled the trigger, that is what should be done.
You are blaming religion for people making illogical, irrational, or just plain ignorant/stupid decisions and/or actions. I choose to blame the individuals, as if they are if they have the mentality to do something and then hide behind religion, it should not be blamed on the religion, but rather on the individuals.

As for arguing that believing in something because there is no evidence is illogical, well, that is much of what belief is. If nobody believed in something without evidence at first, then nearly nothing would have been accomplished in the history of anything. The proof or evidence of an invisible sky-daddy is likely nigh-on impossible to find other than a bunch of old books that say so, but, nevertheless, it shouldn't be discouraged simply because "We cannot see, therefore it does not exist."

That idea, in and of itself, seems to be more closeminded and irrational than most religions I've seen or heard of, and is something that I simply can not agree with.
