Sexism=Comedy?

Have you ever watched a movie and thought, "Wow, that's offensive!"? For me, this happened a few weeks ago while watching Monty Python and the Holy Grail. This film, directed by Terry Gilliam and Terry Jones, members of the comedy group Monty Python, is a 1975 British comedy. I should have known. But, determined to experience this cultural icon, I watched the movie. It was stupid and pointless and only funny in certain small parts.
What upset me though was the blatantly sexist portrayal of females in this film. The only scene containing women is scene 11, in which Sir Galahad the Chaste catches a vision of the Holy Grail above the Castle Anthrax. Upon entering the castle, he is bombarded by young floozies who try to tempt and seduce the poor knight. He tries to resist and asks to see the Holy Grail, please let him see the Holy Grail, oh he only wants to find the Holy Grail which appeared above their castle. When he mentions his vision, one of the girls, admits that her twin sister Zoot, who invited him into their dwelling, had been "setting alight to [their] beacon, which, [she] just remembered, [was] grail-shaped." Galahad realized he'd been duped and quickly began to fall for their permiscuous pleas. Before he could enjoy their company, Sir Lancelot drug him away in a "rescue" attempt.
In addition to the crude references, I was upset to see that the general public is amused by powerless, dependent women whose only desire is sex. Women can be intelligent, powerful people, when they choose to be. People annoy me when they settle for less than their potential. And when their settling reflects badly on me, I become indignant. Because of stupid, shallow girls, I have to work twice as hard to prove myself as a respectable, honorable, strong woman.
