There is video evidence that he exists! How can you deny that?

Actually you do not believe in the FSM, because you cannot believe in something you know to be created for the sole purpose of creating a straw man argument.

Hence, like all followers of the Flying Spaghetti Monster, you are a liar and in bad faith - which lie is your fundamental creed. Questions: Do you trust a liar, especially in matters of ultimate reality and importance? Is the point to win converts or be right?

At the same time, FSM followers are also examples of the paradoxical sentence: "I am lying." Because it is obvious from the context that you do not and cannot believe in the FSM, you are publicly declaring yourself to be a liar, a heretic, and someone insensitive to the sacred beliefs of others. This begs the question of what you do believe, which seems to be that stupid people don't deserve respect, but ridicule.

While this is politically incorrect and tactically questionable, at least it is honest. And remember, some chickens come home to roost.
