Honestly, I wish they were off the table regardless of who is in attendance. They're rarely funny, and they add nothing to the conversation.

Oh wait, that goes for everything you say, so just stop talking.

Sexual jokes can be very funny if told correctly, in a non-discriminating fashion, in the right context to the right people. That also means that they can backfire horribly, especially if random people around. To me, thats not even a question of sexism, many feel uncomfortable if that happens, regardless of gender.

An open space conference certainly never is the right place. Also, cheap jokes about "dongles" are never worth it... please, keep it classy...

There it is. Certainly doesn't warrant people having their privacy violated.

I'd say so - but that doesn't answer the harder question: What is a sexual joke? That matter is open to interpretation and that's where public shaming becomes a problem: The individual that's the most easily offended gets to lay the blame.
