watching pornography leads to the corruption of mind, forcing one to think lustful and sinful thoughts.
Not really. I don't sexually desire anyone other than my girlfriend. I've watched porn, but I've never seriously desired ANY of those women.
If you witness a murder, are you likely to be traumatised by it?
Of course, but it won't necessarily drive you to murder.
If you are constantly bombarded by images of food, are you likely to become hungry?
Yes, but you're not necessarily likely to steal food.
I'm a vegetarian, but I work at a place that sells a TON of meat, so I'm around it all the time. I have no desire to go back to eating meat.
As the visuals become embedded deeper within the mind they spread to the heart and begin creating emotions, cravings toward that activity. Activities which are not permitted.
Not necessarily. I love watching Superhero movies. (Heck, I've got Batman Begins playing in the background right now.) I have no desire whatsoever to become a Superhero. I love watching Mythbusters, but I don't have any desire to join the team. I love playing thief/assassin characters in the Elder Scrolls games, but I have no desire to become a thief or assassin. (I don't even kill bugs if I can help it.) I played Mortal Kombat and Doom as a kid, but I'm a staunch pacifist. (I still very much enjoy those games; heck, I'm currently working on my own set of Doom levels.)
