Pen Jillette on how people generally react when you tell them you're voting third party [ileadliberty.wordpress.com]:
When people say, “you’re wasting your vote,” all they are saying to you is “fuck you.” They’re saying, “you need to support what I believe, don’t support what you believe, you’re wasting your vote by not voting for what I believe.” So when anybody says to you, “if you vote for a third party candidate, you’re throwing away your vote,” your answer must be – two words, and not “Merry Christmas,” – they must be, “fuck you.”
