For me, EnWorld is where I go to have geeky rules discussions with my fellow gamers - kind of like the rules discussions one gets into around the gaming table. On CM I discuss with my fellow gamers things that are totally unrelated to gaming, like politics, religions, the weather, whatever - kind of like the conversations one gets involved around the gaming table waiting for everyone to show up, or after the game, or during a dinner break.
The point, IMHO, is not one of language filters or who's Modding who, but simply keeping discussions on topic.
