I don't mean to pick on you, Ian, but I do find it ironic that you brought up this point as, ummm, the industry you are associated with is well-known for objectifying women and portraying them in only a sexual light. As you said here, it just gets painful after awhile for one sex to be seen in such a singular dimension. Now, I hope, perhaps you can understand some of the objections many of the women have made regarding that topic. They are no different than the objection that you have stated here.
Actually, there are some key and important differences:
Porn is not shown on prime-time TV where it can be absorbed by millions of impressionable minds. It is a highly regulated, highly-restricted genre of entertainment designed for one primary purpose: to induce an erotic response. Sitcoms, of course, are designed to induce a humorous response (at which they don't particularly excel) in a much wider-ranging audience.
Secondly, in no way does porn attempt to portray itself as anything other than fantasy. Most sitcoms make a point of showing a "typical American family", and try to establish themselves as mainstream from the outset.
Thirdly, porn objectifies men and women equally. Sitcoms decidedly do not. Men are the preponderant butt of jokes on sitcoms since 1970. One study that I read in an entertainment industry journal (this was about three, four years ago, and I can't remember which one or which issue, so I'll understand if you discount this) showed an analysis of scripts of 120 sitcoms in the US, Canada and the UK where the male lead was the butt of the joke over 70%
of the time, with an average of like 12 gags per episode. Women got by with just 4.
So while I agree that it may seem ironic that I would bring that up, the real irony is that someone within my industry would even attempt to post on this forum, in this topic, much less attempt to have an informed debate about it.
