The MPAA Thinks You're Stupid

Apparently the MPAA is quite worried that people watching a movie trailer might not understand that a gun pointed at the screen can't actually shoot through the screen. The organization is forcing preview trailers that show someone pointing a gun directly at the screen to actually change the video or cut that scene out of the ad. As the report at the AV Club asks, is the MPAA worried that someone from a century ago who's never seen TV or a movie is going to suddenly show up and freak out? Anyone who's seen the movie This Film Is Not Yet Rated knows that the MPAA works in mysterious ways, but this just seems ridiculous.
