Ok, when there is a graph based on NPD data that looks like this....
And someone makes an argument about the sales similarities of the PS3 and the GC I have to ask who really finds it to be illogical, illconcieved, or even fanboyism??
Its a legitimate topic of discussion, and a reasonable and defendable position to take. If someone goes over the top, flames, trolls, etc...then you step in. But to warn him for having this discussion is overstepping your bounds. If his position were as silly as you claim then it would easily be shown with a few logical arguments.
If you want to start warning and banning people for Fanboyism and Lack of logic, then please get that added to the rules of the site before you start doling out punishment. And you can also expect to be put in the middle of many "shitstorms" as you are forced to make subjective decision after subjective decision with constant backlash from each and every one. Its a nice thought in theory, but enforcement simply isn't practical short of an iron fist, and that would be even worse.
