Here's a hypo, and maybe that pornlaw dude can give his feedback:

What if, in the next American Gokkun or whatever, a big banner was hung in the back that said "George Bush is a mass murderer", or, right before the final coup de splooge, the whore gave a speech about Darfur? Wouldn't that pretty much make a film ironclad-safe from an obscenity charge?

Of course, that would kill sales in Red States, but still, just sayin...
