Most of them pretty blatantly are. Go say those things to women you know and see how they react. And why are you more worried about a double standard that may or may not exist rather than the actual transgression that occurred?
Now there's thought police working! Based on the five or six quotes the article provided, I only thought one was blatantly inappropriate. They mentioned the quote, "she's a walking std." Really? That's mysoggynistic? Anyone who has a problem with this needs their head checked. If anything, they are saved from getting an std by someone saying this and avoiding the promiscuous individual. Every single men's sports team has said these things at one time or another. Guaranteed. The difference here is that it's written in an email, so there's "proof." Sure, we should not be racist or hateful towards a group. But there also a line between joking and hate. Also a double standard that no women's team would ever be punished for their crazy emails about guys.
FWIW My team didn't make statements like that. Sorry to burst your bubble, but it's really not that difficult to avoid racist and misogynistic jokes.
