I think the idea that social or cultural conservatives are generally people who are afraid of sex is little more than a gross caricature. As I've tried to demonstrate, I equally think a lot of self-professed "sexually liberated" people are, in fact, the ones most likely to feel actual fear for sex, because their attempts to make sex mundane are usually about removing the danger, immediacy and emotionality of sex-- that is, the things that make sex so special in the first place. When I hear someone talking about a naked party, sometimes, they may just think that's a way to have a good time, although frankly I think the average naked human, even a particularly attractive one, isn't something you'd like to look at in most social contexts. Very often, though, I think people who are interested in naked parties or the like are people who are paradoxically terrified of sex. They're attempting to de-eroticize shared nakedness. That's not liberating sex from anything, it's robbing sex of its power.
I do think, however, that conservatives allow general unease and fear about sex to carry a lot of rhetorical water for them. It seems to me that often enough, conservatives can just sort of invoke sexual ephemera and conjure emotional reactions, out of proportion with what they've actually proved logically. We're evolutionarily and culturally cued to react to invocations of sex, and I wouldn't want to change that. But I think conservatives, when agitating against this or that current sexual practice, use that general sense of heightened emotionality or stress to rhetorical advantage in a way that doesn't actually benefit the conversation.
I'm not quite accusing James Polous of doing this here. My assumption is just that James is hearkening to previous posts where he's already laid the groundwork of why bisexuality is bad. James certainly isn't one to not do the necessary intellectual homework. But I would have appreciated a link to get at his actual arguments, here. Invoking the painfully obvious does us little good. James has a pretty strong case for the origins of bisexual affect, although I can't accept it on the grounds that I don't believe in one person or another judging the internal sexual and emotional content of another. More to the point, though, that doesn't get us anywhere about why this is all to our detriment as a society.
Of note here is probably my philosophical stance that the best, most humane and liberating framework for understanding human sexuality is to think in terms of sexual behaviors and not sexual orientations.
Update: Just about everyone in comments, or near enough, is telling my I'm a moron for this post. I don't know, I think I'm on to something here. Look I'm not saying "don't go to naked parties, it's immoral." I'm saying "I won't go to a naked party, because I don't think the people involved are accomplishing what they think they're accomplishing; and anyway, I want to keep shared nudity for sex, because I value sex."
