No, it shouldn't be moderated. I also don't believe it really refers to the games themselves as much as it does a particular demographic. Games like CoD or Madden can be played by anyone, not just by a certain group, so anyone trying to pigeonhole them that way will just look ignorant, the same as someone trying to link platformers with children.
That being said, I consider the practice of dissing one genre or another to be asinine and childish. It's a bit amusing to watch people pout because certain genres sell millions of units than their own favorite genre but it's also really annoying. If someone doesn't like FPS games then all they bloody have to do is NOT PLAY THEM. Instead, some people choose to whine about how developers need to switch to other genres, which is silly since this is the most diverse generation we've ever had.
And, yeah, I'm mostly looking at the platformer elitists who think you can only have fun if a game centers around jumping.
