The "No True Scotsman fallacy" goes like this:
Smith: All Scotsmen are loyal and brave.
Jones: But McDougal over there is a Scotsman, and he was arrested by his commanding officer for running from the enemy.
Smith: Well, if that's right, it just shows that McDougal wasn't a TRUE Scotsman.
This is idiocy
As one famous Muslim said:
Social justice warriors: all the intellectual depth of a Muhammad Ali, without the humor.
