Sexism (but don’t worry it’s funny)

Today I sat down in front of my new Sky tv and chose to watch two sitcoms that I’ve heard high praise for from others; one was Everybody Loves Raymond and the other was Two and a Half Men. I was shocked at the level of sexism in both these supposedly funny shows.
In the first one the only two female members of the cast are both housewives and both seem fine with their fat lazy do-nothing-and-then-moan-about-it husbands. Is this really the type of message the show wants to send? That it’s OK to act like a gigantic arsehole (if you’re a man) because the women will put up with this until you say some remotely placatory statement designed to shut them up and they’ll be happy? Please feel free to tell me if I’m missing some ironic point here, I have only watched one episode.
In the second sitcom, Two and a Half Men the entire premise of the show seems to be based around the fact that unbelievably attractive women are willing to throw themselves at an aging (I’m sorry but he is) Charlie Sheen while his Nice Guy brother (I open doors for women, I respect them, why won’t they have sex with me?) has a shrill harpy wife who of course plugs him for all the child support money she can in her wicked woman way. Is it just me or are these shows really as sexist as they first appear?? All comments welcome x
