I am opposed to stupid debates. People would debate anything, if they have enough time on their hands, but pointless debates are still a waste of time.
An issue is only worth acknowledging when it actually exists. There is no point in arguing whether Mass Effect provided the players with an opportunity to have sex with anything they wanted without consent. But FOX news still tried to blow a huge scandal out of it. Same goes for all (or almost all, since I haven't seen the later ones) Sarkeesian videos. She isn't bringing up valid points. Never ever. She isn't fighting sexism. Those tropes she spoke about are just as valid as any other ones. Saying that writers stop using them, because people may get the wrong idea, is nothing but an ignorant attempt at censorship. Now Sarkeesian simply draws attention to herself by trolling the gamer community, which mostly consists of people who aren't extremely smart. Or even old enough.
So the "isms" are only worth debating if there really is an issue. Accusing a woman of having three sexual partners in Skyrim? Sorry, folks, it's part of the narrative. Sure, it's sexist, but that's the Redguard's misguided social norms, apparently. You can disapprove of the Redguard's culture, but it doesn't give you the right to get offended. On the other hand if the game asked if the game suggested that the player is a slut, then it would be offensive, since the issue is not about in-game characters any more.
The dismembered corpse in bikini from Dead Island? Well, I'm sure it unnerving, but it's not there to say, "hey, man, those women are just a piece of meat". Which, of course, would an extremely sexist message, deserving to be condemned. It demonstrates how awful and disturbing a zombie apocalypse can be by presenting a highly sexual object in a disgusting and nauseating manner. That's exactly what players are looking for in zombie games. You may have no preference for such stuff, but you don't get to argue with them. Just as you don't argue with people who drink tea instead of coffee.
