I'd like to point out something really stupid a woman wrote in an international newspaper.
Why can Buffett get away with saying something like that? Well firstly it barely passes as sexist... this is a sexist joke. Secondly he was using the joke as a metaphor for something else entirely. Lastly, he has given/is giving away $100 billion to charities that include a ton of specific organizations that help women. I think we can cut him a little slack on telling a joke he heard in the 1950's.
