Religion in ALL its forms is complicit in creating the environment where these kind of ranting lunatics are granted the same level of deference and respect that a supposedly "sane" adherent to the same "god" is granted.
You cannot have it both ways. Either your "god" is really all good and powerful and at the same time inept to stop people from bastardizing his message...or the truth is recognized at last - NONE OF IT IS TRUE. There is not a problem of people hijacking religions, there is a problem of religions hijacking people. Just because some of the infected are better at controlling their disease it does not make them any less a part of the overall problem.
I am sick to death of these assclown fundamentalists in all religions, but they are merely the carnival barkers. What really needs to happen is a sober evaluation of the supposed 'benefits' of religion versus its known detriments to society and it should be laughed out of existence.
Holy Spirits? Eternal Life? Flying Horses? Talking Snakes? Virgin Births? Global Floods? Infinite Reincarnations? Holy Books? Immutable Truths? Its ALL BULLSHIT and it's too easy to point at the vocal asshats and say "THEY ARE THE PROBLEM!!!" and turn a blind eye to people who believe the exact same things but are more circumspect about it.
Whether its a Christian asshole screaming "KILL THE GAYS!!!" or a Muslim fanatic screaming "Allahu Akbar!!!" or any other adherent murmuring "AMEN!!" under their breath....its all cut from the same cloth, its all cause by the same pathogen - religion.
Edwin Starr's classic "WAR! (what is it good for?)" song needs an update..."Religion! What is it good for? Absolutely NOTHING!!"
