I hear what you're saying, Adam. For me personally, it gets annoying to hear the same damm complaints over and over again. I don't so much mind it when it is a fresh voice making the complaint: such players, as I see it, are not familiar enough with the game theory of COD to know better. Which brings me to why we can't dismiss those that "don't get it." Having to defend our positions over and over allows us to remember why we have those positions.
Really what the community needs to learn is that critical thought =/= criticizing others.
