Rüdiger Weida, a.k.a. Bruder Spaghettus explains his practice of Pastafarianism in this short, entertaining documentary by filmmaker Alex Alford:
… when I actually met Rüdiger I discovered there was much more to his story than initially met the eye. As a student growing up in oppressive East Germany post-WWII, he fell in love with satire as a means of speaking out against an unjust government. In fact, this led to him being aggressively spied on by the German secret police (and boy, does he have many crazy stories about this). Now, later in life, he has found satire through Pastafarianism as a way to speak out against a new enemy – the German church.
