I'm trying to help Joeboy understand why sexual content can trigger legitimate fears.
Note that at this very conference, there was other inappropriate stuff going on:

So although I agree that Adira was in no immediate danger, I think she was right to see jokes like that as being part of an environment that alienates women and enables problematic behavior.
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.
I understand you don't get it. I'm saying that's partly because you don't have a visceral fear of sexual assault. You also probably don't have much experience with unwanted sexual advances. And you've probably never been sexually harassed. You also may not have experienced being a visibly different minority in a situation where that raises your risk of unpleasantness or violence.
I don't think the jokes themselves were scary. I doubt Adira did either. But sexualization of a professional environment can be scary. So we are finally starting to say that it's not allowed at tech conferences.
