Now for the hard part! For this comparison to make any point in your favor, you need to show how there's a kind of language used in Sports Illustrated, etc., that most men here consider beyond the pale in its offensiveness, no matter who uses it. Can you do it? No? Then you don't have a point.

While it's true that I probably can't find an example of something most men here would find "beyond-the-pale offensive," I don't agree that that's the correct standard to apply here. If I'm reading you correctly, you're saying that Cosmo is evidence that Alicorn's reactions are not gender-typical, and that therefore the fact that Alicorn was offended by some behavior, doesn't tell us that that behavior discourages potential female users. But the fact that P(Cosmo-reader|female)!=P(female|Cosmo-reader) does seem relevant here, because honestly, Less Wrong's potential female user base is probably not primarily composed of the type of women who read Cosmo; probably, it's primarily composed of women like Alicorn. We really are drawing from the tails here. I made an analogy: I said that mainstream women's magazines aren't representative of the women here, just as men's magazines aren't representative of the men here, and you seem to be pointing out that the analogy isn't perfectly symmetrical, saying that there's nothing in the mainstream men's magazines that would offend a majority of the men here to such a degree as Alicorn was offended by what she perceived as objectification, which you are saying is condoned by mainstream women's magazines. Well, I agree that the situation isn't perfectly symmetrical: gender issues are never perfectly symmetrical. But the analogy still seemed worth making. For what it's worth, I'm male, and I'm frequently offended or annoyed by mainstream men's culture claiming to represent the interests of men-in-general, when they certainly don't represent me.
