Underestimated the intelligence? More like overestimated. The fact that we are having a discussion about the possibility of violent video games causing real work violence is a product of the fact that some people are just too stupid to realize that it's just a game.
Shoddy reporting at best. Some people on the internet joke about recent mass murderers and their high scores or k/d ratio but to say that video games made him think that murdering kids was a game is simply foolish.
This seems like much more of an issue of "I am looking for ways to be offended because I'm different" than an actual issue. You want a game to adress these issues when i would imagine few if any members of the team are openly gay and probably none of them have gender identity disorders.
The taboo and mature themes he is speaking of are actually the basic principles of coherent story telling which have been absent from all previous MGS games.
