How is rape porn any different than watching violent movies? Both depict illegal acts. Why is one okay, but the other not? The act of rape is illegal, why isn't that enough?
There's quite a difference in degree isn't there? Violent movies typically feature death but briefly and without detail. Rape porn involves detailed and explicit humiliation of a single subject.
Movies of that nature would face the same uproar, and indeed have (the idea of 'snuff films')
Torture Porn - A splatter film or gore film is a sub-genre of horror film that deliberately focuses on graphic portrayals of gore and graphic violence[1]
Some are even torture porn with explicitly detailed and violent rape scenes[2]. These are also planned to be banned if I am not mistaken.[3]
