Islam does not demand people be any more brutal than Christianity. Jihad is a struggle. Jihad means many things, not just a struggle against the west. just like the "ethnic cleansing" that took place by the Christians against the Muslims in Kosovo, religion is preached by men who are fallible. People of all religions have done terrible things to each other. Abu Musab al Zarqawi, the al Qaeda in Iraq guy who claimed responsibility for all those beheadings, was absolutely in violation of the Koran. Islam does preach all people on earth must be converted to islam or killed, but that really isn't far from old testament Christianity.
