All of the big organised religions have tried to claim they are all about peace.
Unfortunately, history shows they are all divisive, self serving and dangerous. Christianity has blood on its hand in Africa and South America. The Hindus in India and the Buddists are not averse to a bit of massacring to promote their cause. Even the Jews commit atrovities on the palestinians. And yes, Islam fight its holy wars and turns a blind eye to terrorism.
They are all the same, because it is about power and influence. The Islamists are no worse nor no better than the rest.
