The president is, of course being chastised for not saying this was "Islamist" terrorism.  There is no doubt  that this deranged killer THOUGHT he was acting in the name of Islam and even gave credit to Isis.

What do actual American Muslims  leaders  have to say about the shooting?
"The head of the Council on American-Islamic Relations urged politicians not to "score points" or "exploit fear" in the aftermath of the attack. Nihad Awad said: 'This is the time for unity and faith."
"Homophobia, transphobia, Islamaphobia are interconnected systems"
In a direct message to IS, who have said they are behind the attack, Mr Awad said: "How would you stand before God and answer to your crimes against thousands of innocent people?
"You do not speak for us. You do not represent us. You are an aberration."
(of course, the Muslim-bashers will turn this in to an excuse to attack CAIR)
