We've come around to the idea that anything crude is sexist and misogynistic and this just isn't the case. That concept in and of itself is sexist, because we (men) assume that women are too delicate to handle this stuff. We haven't stopped telling the dirty jokes at work, we just look over our shoulders to make sure the women aren't around before we do. Which creates an environment of exclusion.
Instead we should just stop telling the dirty jokes at work, because they aren't appropriate for work.
These jerks should never have even CONSIDERED presenting this app, because it's offensive. Offensive to women, men, people with devout religious beliefs, investors who took the time to listen to these presentations, and the list goes on.
Basically, it's a question of participation vs. objectification--of being in on the joke vs. being the butt of the joke.
(My point here is the term, not the man.)
The question has been well-covered in a related discussion here: https://news.ycombinator.com/item?id=6352595
