Scrap, it's not "islamic bullshit", it's just a deranged mind. Which is a lot if there's explosives but it's not about the religion, it's about the nutcases that interpret it.
Islam, along with all other Abrahamic Religions (Jews, Christians, Mormons, etc...) are the products of deranged minds. These Ideologies, at their root, have a form of Orwellian doublethink. The holy books all contain internal contradictions so that the religion can be re-interpreted in a different manner, at the drop of a hat, for whatever suits the purposes of the clerical class.
When you add to this chameleon like religion, the human tribalistic mentality of "Us vs Them", you have a recipie for unparalleled violence. It wasn't so long ago, that Christianity behaved in the same way. It was the Secular Humanism Movement, born out of the Renaissance, that forced Christianity to behave in a more civilized manner. This hasn't happened in Islamic culture yet, and likely won't happen any time soon.
