I would let it go because there is this thing called free speech and its better to not entertain foolish people. People must have lower I.Q's these days because its pretty apparent that any attention is still attention and thats what shitty people seek. Its been a staple in media that even bad publicity is still publicity. You tell someone something bad about another and often times they won't stray away but instead try to find out for themselves. Look at how much media attention Ozzy Osbourne got over the claims of him biting the head off a bat.
