The rape and misogyny in gaming culture is what the subject is all about though. A lot of the problem associated with the word 'rape' as it is used to mean a general statement 'I got you really good'. How it is so casually thrown around. People who have been deeply emotionally and mentally scarred by rape (which is not every person who has been raped, but it is a lot) does not want or need to be reminded of it. It is not so much that everyone needs to walk on eggshells around all people for fear of possibly hurting them, it is a simple lack of empathy and understanding for our fellow human beings. If someone gets hurt or offended by something you say.. try this. STOP SAYING IT AROUND THEM. I'm not saying don't use the word at all. But if you know something is hurting somebody, then stop doing it to them or around them. Free speech is fine and wonderful, but take responsibility for what you do. It is not a free pass to say whatever you want and nobody can complain about it.
For the other thing brought up... Why is rape worse than murder? Because most people survive rape, and not murder. The immediacy of being the victim of the crime is much worse than observing it. Not to say that those who witness horrible crimes don't have their own issues to work with. But rape survivors have to live with the crime and pain of it every day. Some people can push it aside. Some people find it a lot more difficult. And the culture of victim blaming around rape makes it all the much worse, and why many rape survivors don't talk about it. Many people, even authority figures like the police or people you would turn to like friends or family will look at a survivor and say 'well, what did you do wrong for this to happen to you?' And often not in so nice a way either. Survivors suffer through a lot of pain, mental anguish and emotional scarring that quite frankly, murder victims do not. The friends and family of any violent crime suffers, but it is several degrees less than the suffering of the person who lives through it.
Talking about and depicting these issues in games, books or movies is fine... So long as it is done respectfully. Something that is sadly missing in a lot of media, as it is in life. And also, if you are a survivor and you know a game or movie or whatever include a scene that you will find triggers your PTSD, then you know to avoid it. If you know, of course. I wanted to watch the Girl with the Dragonfly Tattoo until I found out about the rape scene in it. I almost didn't make it through the first half hour of Sucker Punch because many of the themes presented early were stomping all over my triggers. By the time the first action scene happened, I was shaking in my seat, sick to my stomach and ready to run out of the theater because of the pain and emotion the scenes brought up. Even thinking about it leaves me cold and sick and makes it hard to talk about.
But at least if it is part of the media and we know about it, survivors can avoid the situation they know will cause them stress. Or at the very least once they feel the terror and pain starting, they can turn it off, put the book down and walk away. When dealing with people who use words that trigger casually, in games or whatever.. we don't really have that escape. Asking someone to stop is usually met with derision and mockery, often with an increased usage of the trigger, and being told you should 'just get over it' or 'it is just a word.' That is the issue here. It is NOT just a word, it is a reminder of a horrible, probably the most painful thing that ever happened to you. And it isn't easy to 'just get over' or you would have done so by now. From experience, I can say that the mental and emotional scars of a traumatic event last much longer than the physical pain.
So please, I offer up my plea.... think of other people when you say things. Much like you wouldn't tell the survivor of a horrible accident who lost a leg to 'just walk it off', a rape survivor, or anyone who has suffered a horrific incident that leaves them with mental scars, should have their limits and triggers respected. Does it really hurt you to not say 'I raped you!' when you beat someone at a game if you know or suspect someone there is bothered by it? Because I can guarantee that it does hurt someone who is a survivor.
