What is it about Muslim religion that terrorists around the world brutally kill their own countrymen?
I do not think it teaches Peace for all. It advocates the use of force and terror for the cause of religion. And that makes it the wrong faith. As some one who does not practise the religion, it might sound harsh and judgemental about that religion, which i am loath to do, it is a fact that jihad gives them a moral ground to justify such acts of terror and reprisal against the imaginary acts of injustice. If there is a single instance of justification in its theology for resorting to reprisal killings, such a faith is an evil faith. For the sake of humanity and for God, it needs either correction or extinction.
