You cannot quote the religious texts to vindicate Islam! You have to look at the reality, the harsh facts. And whatever the reasons be the fact is... Islam is what unites the terrorists. The terrorists use Islam to brainwash people and involve Muslims into perpetrating the terrorist acts. And it is not a new phenomenon, the extremism in Islam far overshadows any other religion...and Muslim invaders, militants, terrorists had been terrorizing other people for hundreds of years. If only they could use their energy and resources for constructing their community, rather than destructing others, their children could hope for a better life and many innocent lives would be spared.
