If you have a problem with people using a certain word, just air your opinion about it.
But think about the reaction you would receive if you started trying to openly confront people online who use this word.
Let's take a normal Xbox live session of Halo or CoD. A few people are doing quite well, and they are the kind of loud, big mouthed people who like to announce their dominance to others, so they start bragging. "Man, I'm fucking raping these scrubs. Look at how much we're raping, guys." Take into account the kind of people who would commonly use the word "rape" in this way on a normal basis.
Now, you try and talk to these people about using that word in that manner. "Hey guys, that's not cool by me. Saying that could be offensive to people."
Saying something along those lines would provoke a reaction similar to this: "What's wrong, pussy? Did you get raped as a kid or something? Hahaha!"
Now, not to say that this situation is justifiable, but to confront the sort of people that use that term in that manner regularly would just end in ridicule.
I agree that the word 'rape' can be offensive to some people, which is why I try my best not to use it openly.
