Trying to bring this back to the original point, are you then saying that it shouldn't be included in the game?
No, personally i do care much more about game play. Since this doesnt harm game play at all its fine.
However many arguments pro America/US in the game look very biased to me.
From a historical point of view you just have to admit that America/US is a very young country. To me those comparisions America/US to other countries in the game made by some people are weird, the history of those is totally different. The most important difference concerning the game is that the roots of many today Americans are European.
From an objectiv non american view there is really not much need for any other 'American' wonders beside 'The Statue of Liberty' to have in the game. For example 'West Point' or 'The Three Gorges Damm' (i guess its in the US ?) might be very famous inside America but they arent outside. Thus to argument with those things pro America/US seems again odd for anyone not living in the US.
For me there is just one good objectiv argument left to have Americans in the game. That is America/US has a dominant position in nowadays world in science,trade and military makes it one of the most important countries for todays world.
The question is, is that enough to put it in the game ? I have severe doubts with that because the games focus lies on developing an empire through the ages and considering this the time period America/US exists is just too short.
Note that from a historical view im not too glad to see civs like Germany either in the game, however this doesnt change anything considering America.
So why did Firaxis put Americans in the game ? Because there is a very strong argument for it which is.
'Im proud of my country and I want to be able to play as it'
I dont think there is anything wrong with that but you should be aware that many of the other arguments are only existing for American people.
