That interpretation sounds odd to me, so I checked wikipedia, which says:
Sexual fetishism, or erotic fetishism, is the sexual arousal brought on by any object, situation or body part not conventionally viewed as being sexual in nature.
'Conventional' seems to be the sticking point. Ankles are conventionally considered sexual in that culture, so it's not a fetish, in that context; it's a cultural difference.
It seems to make the most sense to think of it as a kind of communication - letting someone see your ankle, in that culture, is a communication about your thoughts regarding that person (though what exactly it communicates, I don't know enough to guess on), and the content of that communication is the turn-on. In our culture, the same thing might be communicated by, say, kissing, with similar emotional results. In either case, it's not the form of the communication that seems to matter, but the meaning, whereas in the case of a fetish, the form does matter, and what the action means to the other party (if there's another person involved) doesn't appear to. (Yes, I have some experience in this area. The fetish in question wasn't actually very interesting, and I don't think talking about it specifically will add to the conversation.)
I'm... not quite following. I gave 2 examples of why an educated modern person would not be surprised at Victorian ankles and their reception: that fetishes are known to be arbitrary and to cover just about everything, and that contemporary cultures are close or identical to the Victorians. These were 2 entirely separate examples. I wasn't suggesting that your random Saudi Arabian (or whatever) had a fetish for ankles or something, but that such a person had a genuine erotic response regardless of whether the ankle was exposed deliberately or not.
A Western...
As promised, here is the "Q" part of the Less Wrong Video Q&A with Eliezer Yudkowsky.
The Rules
1) One question per comment (to allow voting to carry more information about people's preferences).
2) Try to be as clear and concise as possible. If your question can't be condensed to a few paragraphs, you should probably ask in a separate post. Make sure you have an actual question somewhere in there (you can bold it to make it easier to scan).
3) Eliezer hasn't been subpoenaed. He will simply ignore the questions he doesn't want to answer, even if they somehow received 3^^^3 votes.
4) If you reference certain things that are online in your question, provide a link.
5) This thread will be open to questions and votes for at least 7 days. After that, it is up to Eliezer to decide when the best time to film his answers will be. [Update: Today, November 18, marks the 7th day since this thread was posted. If you haven't already done so, now would be a good time to review the questions and vote for your favorites.]
Suggestions
Don't limit yourself to things that have been mentioned on OB/LW. I expect that this will be the majority of questions, but you shouldn't feel limited to these topics. I've always found that a wide variety of topics makes a Q&A more interesting. If you're uncertain, ask anyway and let the voting sort out the wheat from the chaff.
It's okay to attempt humor (but good luck, it's a tough crowd).
If a discussion breaks out about a question (f.ex. to ask for clarifications) and the original poster decides to modify the question, the top level comment should be updated with the modified question (make it easy to find your question, don't have the latest version buried in a long thread).
Update: Eliezer's video answers to 30 questions from this thread can be found here.
