I'm skipping over it because there are inherent differences in different types of media. A) Video games don't involve real people and B) Sexuality is wired in the mammalian brain in a unique way. We can't generalise so easily as you're suggesting.
If I see an actress in a movie being shot, she's not actually being shot. If I see an actress in a porn movie being choked, she's actually being choked. That's not a question of consent, it's a question of content.
But on that note, have you ever worked a shitty or degrading job and had to do things you found painful because you couldn't afford to say no? I have. It's painful to go through. I can't imagine coupling that with the complex layers of human sexuality.
You're saying it doesn't equate because of consent but that's not the aspect I was equating.
Take a look at the front page of PornHub now. There's a video on there showing a man flashing strangers. Yes, they must be actors, but it's filmed in a way that suggests they're not. There's absolutely nothing there that would promote the idea of consent in the mind of a young viewer.
Yes, maybe parents could watch those videos and explain that it's normal to fantasise and play-act about assault. But I'd hope that at the same time we, as adults, would speak with qualified therapists and try to ascertain the roots of our attraction to forcing our genitals onto unsuspecting women.
Final point: PornHub has only required verification from uploaders since relatively recently, after dozens of women took them to court for hosting their rape videos and after it was widely publicised that there was a good deal of underage rape videos on there. There are still other popular sites such as chatpic.org or videos that happily allow abuse content to circulate without any concern for consent. That's only what's on the open web.
