Of course it&#x27;s not &quot;all Muslisms&quot;. But those who claim &quot;it&#x27;s only the terrorists&quot; or &quot;it&#x27;s all politics&quot; do not grasp the scope of the problem, ie that globally speaking, a significant number of adherents of Islam hold ideas that are incompatible with an open society.<p>If you naively extrapolate from the 2013 Pew Poll <i>The World’s Muslims: Religion, Politics and Society</i> (which in principle represents nations with a total Muslim population of about 1 billion), 40% of these think you should be killed for leaving Islam.<p>To me, that&#x27;s a scary number.
