I strongly disagree, we have too much of that already. Half of what's damaging gaming right now is that the gaming media (as a whole) allows too many people to yell and scream their dissenting opinions, at a time when people need to step back and consider things a lot more rationally. Games tend to get tied into a lot more issues than they really should, especially seeing as they have unfortunately become a platform some people like to use to express their own idealogy and politics, and then get all upset when someone else who does the same and happens to disagree with them vehemently.
As a sort of point, look at the current state of games where all the yelling, screaming, and political posturing has created an environment where pretty much the only enemies you can safely use are zombies, Nazis, and aliens. Try and do a game involving say Russians, Chinese, Arabs, or whatever else, then all of a sudden screaming dissenters will appear from the woodwork and try and tear you down for being an evil bigot. The kind of reaction which hit say "Resident Evil 5" for showing tribesmen as tribesmen (and nothing all that different from national geographic) and pretty much ensured game companies aren't going to be in a big hurry to set many more games in Africa. Not to mention comments (some joking, many not) about Uncharted being racist, and the "pulp" type adventure vibe used in that game and Lara Croft being "offensive" to indigenous peoples because these guys raid ancient ruins and treasures for their own benefit.
"South Park: The Stick Of Truth" actually skewered this, and even outright spelled out what they were mocking. Not to mention even making a joke that when using the most sanitary and politically correct enemy available: the tired "Nazi Zombie" someone STILL objected (a german doctor who claims it was an offensive stereotype before getting gunned down), perhaps kind of ironic given that even with something this tired Germany called for this to be censored, making that scene even more funny given how oddly prophetic it was of the entire thing.
The point is more academic detachment is what's needed, not people shouting fire about how this is offensive, or that's offensive, or how a game shouldn't do this, or that, or the other things. It gets to the point where if current trends continue we're going to probably have to go back to pong. What we need actually is more of a concerted effort to keep that kind of thing out of gaming entirely. An actual effort should be made to pretty much deny any kind of large platform to people who want to make a message about video games and their content, whether it's sexism, racism, graphic violence, actual sex, or whatever else. Talk about the game, what it does, and whether it works, not what your opinion is about Nathan Drake stealing an Incan treasure, followed by a paragraph of hang wringing about the rights of indigenous peoples, people who don't like old school pulp-treasure hunting probably aren't considering the game to begin with, in order to want to know if it works or not, which is what they are looking to the game media for information on.
In short what I think we need is far more reviewers, and a lot less critics. Sure a modern FPS shooter might absolutely reek of pro-American jingoism and seemingly encourage military adventurism, especially to someone who doesn't like the US. The heroic American Flag imagery in the promotions, voiceovers by guys like Oliver North (in some cases), and similar things make that bloody obvious. The guy who bothers to look it up wants to know if the game is decent at what it does, not your opinion of the subject matter, and whether or not it should be selling millions upon millions of copies globally in your opinion. My opinion is exactly the opposite of what's posited in the article.
I say this largely because I've occasionally found it hard to really get good information on a game (including one that has already sold tons of copies, making opinions about content irrelevant), because it seems every source wants to spend the majority of the time ranting about the premise/content either to attack it or defend it. I'm not a big fan of shooters though, I just use them as the common example of a game type that falls prey to this.
