Because people with certain biases who want to ignore evidence and blame this all on Islam to define &quot;these terrorist attacks&quot; in a way that excludes many similar attacks? We&#x27;ve been averaging about one mass shooting a day in the U.S. There are so many that I&#x27;d forgotten about some major recent ones, like the Umpqua Community College Shooting just a month ago.<p>These usually get planned well in advance by some very sick people who are trying to kill as many people as they can and go out in a blaze of glory. Sure, the existence of opportunistic terrorists networks that get these people to coordinate their attacks and stamp a ideology on them tends to mean that the one day body count is higher for a particular incident. Still, the body count per attacker is often comparable, it&#x27;s just that the attacks happen on the same day instead of a few weeks apart.<p>But yeah, if we ignore the non-Muslims who do things like this we can say it&#x27;s all the fault of Muslims.
