Do Quranic verses inseminate terrorism?

I don’t want to sound political but we cannot dismiss objectively verifiable evidence vindicating acts of barbarism perpetrated by those groomed in the secular humanist world. Holocaust cannot be just brushed aside a relic of the past, mass extermination of the Bosnians by the Milosevic ruffians is not a fantasy creation, shooting down of the Malaysian passenger plane MH17 with 298 innocent civilians on board is not the work of an Islamic militant inspired by Quranic verses, gruesome torturing and humiliation of prisoners in Abu Ghuraib by the enlightened, liberal and secular soldiers of American had nothing to do scriptural mandate, the indiscriminate brutalities committed in Shabarghan Jail in Afghanistan, under the very nose of ISAF cannot be attributed to any Quranic verses. But the secular humanist will conveniently call these individual acts that constitute exceptions, not the rule. Unquestionably, taking Baslan school children hostages by the Chechen separatists, the killing of journalists by the ISIS, kidnapping of schoolgirls by Boko Haram, the slaughter of Shia community in Baluchistan or bombings of tourists in Bali are all acts of terrorism, which the liberal and the mainstream moderate Islamists alike condemn. But then instead of counting these incidents as acts of a small fraction of Muslim community, they are generalized by the secular camp to either label terrorists as similitude of all Muslims or as manifestation of Quranic sanction for the acts of terror. The point that I want to bring home is this: terrorism does not exclusively emanate from religious scriptures; it can be spurred by any motivating factor, be that belief system such as religion, ideology such as nationalism and racism, or human impulses such as revenge and sadism, or phenomena such as injustice and oppression.
