   They all understand that.   
      
   What you don't understand is that if you assume that a truth predicate   
   exists, then by performing a set series of truth preserving operations   
   we reach the conclusion that the liar paradox does have a truth value.   
      
   Therefore no truth predicate exists.   
      
   Once again, you're proving you don't understand proof by contradiction.

   Only if you first assume a halt decider exists.
