I'm pretty sure most of them don't even really know what the AV industry is like. I mean, most probably know it has to do with sex, but have no clue about any of the sex acts involved (bukkake, gokkun, fera and osouji-fera, 3P and 4P, nakadashi, as well as the more guro acts) to be able to have a strong opinion.
Hmmmm....but even if the girls do have something to say about the issue, I doubt if the higher-ups will let them, especially on something this big. A gag order could be laid upon them anytime.
