He used this in reference to Islam?
I think he needs a change of terminology on this one.
He first used "crusade" and got jumped on heavily. He then used "religion of peace" to calm the masses. He hasn't used that for awhile. It's now islamofascists.
In the past...not today. In fact he used it EVERY time he referred to the religion of the blood thirsty bastards. He's the one that made it part of the American lexicon. Of course most of us who still use it do so with a little more cynicism that the President used.
