Let's look at the root of the problem. At first glance, it looks like this is about Civ 5 Criticism versus Civ 5 Other Discussion. Wich should not to be confused with Civ 5 Trolling versus Civ 5 Civil Discussion, that is too often mixed up with it.
Now, if we did isolate Civ 5 Criticism, Civ 5 Other Discussion (now turned into hegemonic Civ 5 Discussion) will create the illusion that everyone participating in it "likes" the game, effectively censoring opinions of dislike, since those who don't like it, only say it somewhere else. This leaves naysayers with only two options: you either lead a fony double life, criticizing only in the Criticism forum and looking like you have nothing against Civ 5 in the Normal forum; or you resign yourself to criticizing Civ 5 only in the ghetto with the rest of your kind, keeping your head down, 'cuz if you speak your mind in the wrong place, you'll get busted by the cops--err, mods. Does this sound familiar to you?
