OF COURSE there are differences between America and England, everyone knows that! All I'm saying is that these differences are hardly enough to call them totally seperate civilizations - at least not when your job is to divide the whole world into only 18 civilizations.

Damn, I can't see why you're being hounded so bad for a fairly simple point, but I disagree nonetheless. Similarity isn't reason enough to choose a civilization, if that were true, Sparta, Athens, and Macedonia would never be subsumed into a single "Greek" civ, their ways of governing politically, militarily, and economically were as different as you can get. Problem is what's prominent today is the Athenian tradition of education and the memory of Alexander conquering the known civilized world, and they don't conflict, so they're easy to put together.
Even though they're similar, there are enough differences between America and England that America has become the dominant world civ (though China's starting to nip at our heels in a big way), while England's days of near world dominance are long gone.
So you say B, America and england should be combined, I say that your assertion of B implies the notion that similarity is the main criteria for choosing civs, B > C to use symbolic logic, I also say that similarity is not terribly important, ~C, and from that we get the conclusion that they shouldn't be combined, ~B. It's called modus tollens.
I'm arguing that prominence in the modern world (including how much their history captivates us), D, is the main criteria for sperating England and America, A, and that D applies in this situation because the relative prominence of England and America make their potentially slight difference enough to distinguish them.
D > A

You seemed to be just randomly assigning variables to argument points without illustrating their relation or lack thereof, so I hope this clears some of that up.
