All this talk of zombies on the gun forums, the last few years - how did that start?
I haven't seen any zombie movies or read any zombie books, so I must have missed a lot. But I do recall my friends playing that Resident Evil game. Especially the first one, with the gang-rape death scene.
Very simple. It's an implausible end of the world type scenerio. They're mythical monsters like werewolves, vampires or Furby dolls. Plus they're much like Nazis, in movies or video games you can do literally anything to zombies and no one will complain. Impale them, shoot them, cut them to ribbons, whatever. They're a very clear 'bad guy', who can be killed without any remorse or regret on the part of the viewer.
I played Resident Evil and I am very unaware of any rape scene.
