being that it's apparently my day to wear the humorless feminist hat, please allow me to poke you in the ass and make you go read this.

this seems to be an archive of a mailing list.

anyhow. the good part.

Feminist Jokes: "The purpose of humor which looks at specific groups is to make fun of that group and help maintain the status quo. This type of humor only works if there are these stereotyped perceptions of a specific group.
To see if humor is stereotyped, try changing the gender, race, religion, etc. and if if does not work when you do that, then you are playing to the stereotype and helping to maintain those false images."
