I never understand why those who profess a theistic religion feel compelled to attack those who they consider "sacrilegious" or "blasphemous". If their God is so all-powerful and all-knowing, cannot He do something about this problem. Cannot this God just boom down from Heaven to these blasphemers to shape up?
I think the attackers themselves are insecure in their own beliefs and are the "sacrilegious" or "blasphemous" ones. They think beliefs different from their own are threat to their beliefs. They have the hubris to think they know better than God.
They also are the greatest threat to their own beliefs. Why would peaceful people follow their beliefs? Or why should peaceful people of any belief respect and tolerate the beliefs of the attackers?
