I disagree that Giant Bomb should steer completely clear of any and all social issues within video games. However I do feel that such conversations can sometimes drown out everything else. You've got entire game boards that barely get any discussion, yet as soon as sexism is brought up then the forums are on fire with comments and thread views.
The perfect example would be Patrick's Worth Reading feature. So many articles and videos to inspire discussion, and yet should there be a social issue article amongst the lot then that's basically all 9/10 people will be talking about.
