Dominion of Canada -> Canada (I think they dropped "Dominion of" some time ago, though)
Kingdom of the Netherlands -> Netherlands
Federal Republic of Germany -> Germany
It's a fairly common abbreviation style, and USA is the only country that has "America" in its name.
If the OP thinks that the USA is any more of a monoculture than Europe is, perhaps he should spend some time in Manhattan followed by some time in Luckenbach, Texas. :-)

I don't have enough information to comment on your example, but I suppose that in every small village on Earth you'll always find the progressive and the conservative guy, and you'll always find a different environment in a big city than in the countryside.
My comment was more to point out that in Europe each people still has his uniqueness. You know how Swiss people are proud of their neutrality, Finnish school system is (one of) the best in the world, Englishmen love their queen, Greeks invented democracy and Italians are immune to Stendhal Syndrome? Well, none of those sentence makes any sense if you substitute the national adjective with "European".
Europe being not a nation is not only a matter of traditions, but of everyday life as well. We don't share a television system, which would be anyway complicated by the multitude of languages. We don't follow political debates in other countries, and newspapers will report about foreign election only for a handful of states or when an extremist party wins. We have the football European Champions League final, but it's nowhere like what I heard about the Super Bowl, with stars and celebrities, because we don't share stars and celebrities.
Maybe this is just a case of "far away, thus homogeneous". For example, some time ago I was talking about south-Asian cuisine, when suddenly I found myself wondering how I could talk about a south-Asian cuisine. Does a south-Asian cuisine even exist? What would I do if I traveled to China and entered a "European" restaurant serving both pizza and haggis? I'd run away while screaming!
Everything you said about the uniqueness of European countries applies to the uniqueness of American states or regions, so I'd say it's case of "far away, thus homogeneous".
Citizens of the USA are Americans.
We're happy this bit of reality made you smile.
