Unfortunately, Shrek II is germane to this discussion. I have not seen it, but understand that it has some references to sexually deviant behavior as a source of humor.
The problem is that popular culture is where ideas become "normalized". Who would have thought 20 years ago that there would be umpteen network shows that included gay behavior as part of the plotline. Or, for that matter, the multiple sexual encounters of a bunch of women? Or that any reference to Jesus, other than as a swear word of course, would be come culturally unacceptable?
There are some interesting articles out there about the progression of ideas. If it were only an incidental reference in Shrek II, wouldn't be a problem, but trust me - that won't be where it ends.
I agree. Taken alone it means nothing, but as part of a bigger picture it means much more - a shift to legal and moral acceptance of deviant behavior. The supreme court, liberal federal courts, state supreme courts, and the teacher's unions, not to mention the pc/diversity industry crowd, are all to blame. Fortunately, nature is on our side (std's have a way of showing up if you have a lot of sex with a lot of different people).
