I think the best argument against the dancers is that it is tasteless -- or at least seems so to most of the readers here. I honestly don't know if it seemed tasteless to conference attendees or not. I also don't know if it was a major part of the conference or could easily be skipped by those who didn't like it.
I try to be an easy-going guy. Nobody is being harmed here. More troubling is the tendency to mouth-off about "easy" things like this while saying things like "every culture is okay" when it comes to things like the secret police or freedom of information. That just seems completely moronic to me.
Unfortunately it has been decided (in the rest of the comments) that we're not allowed to do anything about, or even comment on, any of these problems, even if done by Western companies in foreign lands, because to do so would be cultural imperialism.
