Next time someone says "You should respect peoples views on religion", show them this:
AQ affiliates on the rebel side against Assad murder suspected Sunni truck drivers
Terrorists from the group Islamic State in Iraq and the Levant (ISIL) – a merger of Al-Qaeda fighters in Iraq and Syria – can be seen stopping trucks in Iraq that were headed to Syria. The drivers are forced to exit their trucks and subsequently grilled by a Sunni jihadist on whether they are Sunnis or Shi’ites.
After failing to answer the religious questions correctly to prove that they are Sunnis, they are executed amid cries of "Allahu Akbar!" (God is great).
The video ends with a threat to the "Armies of the Cross in Dabiq," saying they will be burned by the “fire who spark ignited Iraq.” Dabiq is a town near Aleppo where, in the sixteenth century, the Ottoman Empire defeated the Mamluks.
The link above contains a video showing just how revolting these religious thugs are.
