> I think she was right to see jokes like that as being part of an environment that alienates women

I would agree that those jokes could alienate some women and men, and therefore don't contribute to an inclusive environment. And the other stuff in the post you link to sounds crappy. I'm in favour of having a code of conduct, particularly if there's a culture of inappropriateness that needs addressing. I still think your conflation of dick jokes with sexual threat is OTT.
