I am a male gamer who has been playing games for over two decades and even I feel estranged by a majority of the "AAA games" the industry is pumping out these days. My solution is simple: I don't buy them. That said, I admire those that are taking it even further and trying to start an intelligent conversation about how the gaming medium can mature. To try and stop that discussion and, by extension, stunt the growth of such an expressive medium is absurd to me.
People don't (at least, in a free society, shouldn't) get to ban what they don't like, but they can show the damage that certain attitudes cause. The responsible adults among us, including the members of the gaming community, will hopefully see the problem and join in the demand for change. If nothing else, capitalism will step in to help. If there is a market for enjoyable games that don't make the player feel sick to his stomach for the attitudes they portray, someone will step into the void and make games for that market.
However, I'd like to believe that as a society we're enlightened enough to realize when treating people a certain way is simply wrong.
