“No True Muslim” is an informal fallacy, an ad hoc attempt to retain an unreasoned assertion like “Islam means peace”. When faced with a counterexample to a universal claim – like a bunch of guys claiming to belong to the Islamic state who kill a bunch of people and blow themselves up while yelling “Allahu Akbar” and who are later identified by the Islamic State as as Islamic State militants doing things for Islamic reasons – the No True Muslim fallacy will say, “It can’t be about Islam because no Muslim would do such a thing.”
Rather than denying the counterexample or rejecting the original claim, this fallacy modifies the subject of the assertion to exclude the specific case or others like it by rhetoric, without reference to any specific objective rule (“no true Muslim would do such a thing”).
In other words, it is simply a barefaced denial of the reality that is in front of all our eyes.
We are being gaslighted.
