I will never refuse prayers from anyone.  But I wasn't as much disparaging your character as I was your logic.  You can't logically argue that we should believe the Da'esh are "Muslims" just because they claim to be without accepting the equally absurd argument that we should accept the Christian Identity Movement's claims that they're "Christians" just because they claim to be.  And the fact that every time I prove you're wrong at some point in our discussion you attempt to extricate yourself, as you did when you wrongly accused me of supporting the Da'esh, suggests that your own arrogance won't allow you to learn if it contradicts your preconceived notions.  I neither know nor care enough about you to assail your personal character--I WILL point out your poor logic and expressions of willful ignorance, and not apologize for that.
