I agree. It is rather daft. The programme should be switched off or taught to parse words properly.
UK English does not has A S S as a perjorative, as US mangling of innocent words does, but describes an animal like a donkey. F A G is slang for a cigarette. F A N N Y is rude as it refers to different part of the anatomy. That excellent British seaside town S C U N T H O R P E has long been the sacrificial lamb of over zealous internet nannying.
please do something about it sooner rather than later. As Bob has said it can make questions and answers senseless.
Even from a USA dictionary it is not really a rude word:-
Definition of ass
