How do I convince my parents to let me skip school for two days?

In history class we're supposed to go on a field trip to the stupid Holocaust Museum and then have Holocaust survivor speakers come in and talk. I've done my own research and I don't want anything to do with it. I believe the Holocaust is a total exaggeration and is nothing more than a big billion dollar industry set up by the Jews, with all its movies and museums, etc...I wont waste my time with something I don't believe in. I cannot believe my parents, being German Americans like me they should agree with me. How do I convince them to let me stay at home?
