Yesterday, I heard an apparently old joke and shared it with a friend. This friend typically enjoys tasteless humor, so I thought nothing of it.

The joke:

Q: What's the difference between Sarah Palin's mouth and her vagina?

A: Only some of the things that come out of her vagina are retarded.

This joke is obviously offensive for a number of reasons, so it was understandable that she was offended; however, the reason she claimed it was offensive was because it was sexist. Of all the reasons this is offensive, I didn't (and still don't) see how this joke is sexist.

I'm curious what Reddit has to say on the matter!
