OP is on a rant. I only understand half of it. But some things like that picture with the kid playing games and getting it from the adults and the young adult getting it from the older people with the same BS in different words, is how I see the situation. I saw it happen. I was there. 3000 years ago.
The main evidence that I have presented so far is logical: that if a person uses SA as entertainment, they must accept that it is entertaining, which means that they must, on some level, view it as acceptable.
That is not evidence. That is your hypothesis how this works. Exchange SA for murder and apply your hypothesis to all those crime tv shows. Crime is popular entertainment since like forever. So society should have accepted it long ago as socially acceptable. Is this so? No. Hypothesis rejected.
How would playing a game suppress such urges?
How it might do so? You play the game and control the events. You are playing. A pretend sitation in a safe environment. You do a bad thing. You might snigger and lough at the absurdity. Or you might feel bad for hurting some imaginary pixels. Either way, you might take away from it, how you would react in a real sitation and then have fun in the unreal situation and fool around. Not unlike some people go over imaginary discussions while in the shower.
the idea of "blowing off steam" to suppress desires has been accepted as false and damaging
Care to link me to some data about that? And what kind of desires are we talking about. I am not asserting that clinically insane mass rapists can cure their urges with that. I am merely protesting your assertion that playing such a game creates those urges or creates a demand for more, and the data I saw and my own experiences with games suggest that if any, there is the opposite effect of what you described. I for sure do not feel the urge to murder people. And I find guns abhorent. But willingly engage with them in a (virtual) play situation.
Secondly, I demonstrated that feeding addictive behaviors leads that desire to increase
Your premise is an already addicted person and you did not demonstrate, you asserted. Also, addicted to what? SA? Playing games?
The connection you try to make, is, that being addicted to a game with fictional content (or playing that game) will leap over to being addicted, or even try out that thing in real life.
But there is nothing "impossible" about sexually assaulting someone. It can be done. This is an important distinction.
Murder is also very possible. Or stealing cars like in GTA. Wait, so if SA is happening to furry bunnies, it would be ok? It is a game! People know that they play a game. It is a bit condescending to only allow them to see the difference, if it is about Orcs, but not allow them to see the difference, if it is about regular humans.
But this is why I don't think statistics can really tell us the full story. Why did you decide to round to x10? Seems pretty arbitrary to me.
It is. But saying x10 much is easier as 1.34 / 41.8, and it catches more countries. Actual numbers are here https://worldpopulationreview.com/country-rankings/rape-statistics-by-country
You can feed a lot of cultural and statistical bias into those numbers to even them out. But if video games about the crimes are relevant here, I would expect the numbers to be a lot closer together, or rather expect the Japanese number to be bigger and not to be x31 smaller. So I either accept that the video games are not relevant here, or I accept that it has the opposite effect of what you claim.
I do not know the situaion in other countries in regards to the availablility of such video games. Are they very popular in Britain maybe, because they have more than double the amount than the US?
You talk about the "novelty factor" wearing off. This means it becomes normal.
No. It does not become normal in real life! It becomes a seen thing in such games. It's novelty bonus fades. It contributes less to the entertainment.
We could go back and forth sending each other links to studies supporting our opinions for a very long time, and never get anywhere.
I am awaiting a link to something that would support that connection you try to establish. It did not work for fps games decades ago. And for SA specifically, the data contradicts the assertion. The place where those games are known to be readily available for adults has one of the lowest SA rates on the planet.
