I mean, it probably hurt the octopus to have sex with it, but I don't see how possessing octopus porn should be an offense worthy of lawful punishment. It seems a bit too much like reality control to me, if the man wants to fap to pictures of someone fornicating an octopus, so be it! It's so absurd "don't look at this or else you'll have been effected by the brain rotting perversion of octopus porn!" What do they really gain from keeping people from looking at octopus porn? Is punishing them going to somehow make them less likely to jerk off to strange sexual fetishes? Hell no, it's just going to take a big chunk out of their life and torment them, all to make an example of him that having sex with an octopus is wrong, and that watching the porn of it promotes such behavior.
Then again, it really doesn't need to make sense, when you realize that the government will ban things like marijuana, and incarcerate people for having that for no reason. They don't even say why weed is legal. I bet it's illegal for the same reason that all drugs are illegal; because with them then people would start to be too independent minded and think for themselves. I mean think about it, fucking processed sugar, mcdonalds, cigarettes, motorcycles, more guns than we could ever need, all of these things are legal. But somehow weed is going to make the society we live in less safe? I really loathe the government.
