As for your "evidence" from GeekFeminism, you will note that that's a linkspam page, merely linking and quoting, without any commentary. And the quote is not about The Dating Ring, but about the changes that are necessary for the industry to become more diversified. (Yes, there's a lot of irony in this coming from the women who're responsible for this bride-for-sale scheme)
Sounds a lot more like an interest police out to get guys than anything to do with respect for women to me.
This has been rehashed aplenty. Sexual innuendo between two people, when not directed at a third person does not qualify as disrespect to the third person, unless you're trying very hard to feel disrespected.
> It certainly doesn't belong in a K-12 classroom.
If you think it doesn't belong in a K-12 classroom, I seriously doubt you have ever interacted with anyone in high school. Please read the data in this and draw your own conclusions. http://www.guttmacher.org/pubs/FB-ATSRH.html
The answer should be fairly obvious.
As for point 2, the fact that teens are currently taught to be sexist doesn't mean they should be taught to be sexist, or that it's OK. Especially not from adults.
I'm guessing you missed the news over the last couple months of GitHub[1] and Rap Genius[2] each letting a co-founder go?

Meanwhile, Joe Dev who is working 10 hours a day will be fired for saying "Hee hee hee, look at this huge dongle I just got." at a tech conference.
That was Joe Schmoe male developer, who it is acceptable to fire for the slightest of reasons, including making an innocuous joke that wouldn't be out of place in a K-12 classroom. The men who are the customers of this startup are the rich guys in Silicon Valley who are awash in cash and cannot be fired.
The two are worlds apart, don't be under any impression that they mix in any sense whatsoever. Unfortunately, the first group (Joe Schmoe) is squeezed to the max by policing by interest groups like "Geek Feminism" and suchlike. Notably, Geek Feminism seems to have a neutral/positive approach to this Dating Ring thing (http://geekfeminism.org/2013/12/30/happy-new-linkspam-30-dec...) -- the company is referred to as "Y Combinator's first all-female company", and no negative comments.
