Well, it is conservative from the European and even the global perspectives, because both the US Republicans and the US Democrats sit firmly on the right of the political horizon — which shouldn't surprise anyone, given that both parties are owned and controlled by the corporate world, and not in the least by the bankers.
Just because there is a movement of so-called social justice warriors — American culture is really good at coming up with buzzword monikers that can then be abridged into acronyms — who are most likely not going to vote for the US Republican Party, doesn't make this movement left-wing yet. It's a step in that direction, yes, but it's not quite the same thing yet, given that social justice warriors are more about ethics and social equality than about economics and political liberation. Apples and oranges both count as fruits, but they're still different types of fruit.
True socialism is a negligible political orientation within the USA, and those who were accusing Barack Obama of being a socialist were invariably all to be found among the adherents of the US far right. It was just a hyperbolic knee-jerk reaction to Obamacare, because the US far right is simply so self-absorbed that it considers anything outside of their own ideology as socialist or communist, and those two words are still considered expletives in the USA, given that the anti-Soviet propaganda of the (first) Cold War has made sure that there are nary any US Americans who understand what socialism and communism really are.
In addition to that, if political orientation were to be mapped out on a two-dimensional compass with a North-South axis representing authoritarianism versus libertarianism respectively, then both the Democrats and the Republicans would be located in the North-East corner of the compass, i.e. authoritarian and decidedly capitalist-corporatist.
The Democrats are more globalist than the Republicans, but for both parties, the conditio sine qua non is that it must be the USA which sits at the top of the globalist food chain. Or otherwise put, it is actually imperialism shrouded in globalism, whereby the Republicans carry a thinner globalist shroud than the Democrats and allow more of the underlying nationalism to shine through. George H. Bush for instance was a US Republican, but he too was a globalist, albeit with the same underlying principle that the USA — and specifically, the US banking world — had to come out on top of that New World Order.
This nationalism is also reflected in US American culture, in part because of American Exceptionalism and in part because the vast majority of middle class Americans hasn't got the faintest idea on what living in any other type of culture is like, courtesy of the poor US American education system, which was itself engineered to stimulate nationalism and American Exceptionalism.
So the bottom line is that, yes, as a nation and as a society, the US is actually far more conservative than what meets the eye. It's engrained within US culture itself, even though it has gotten there through artificial means — through the stimulation of consumerism, through an insular education system, and through pervasive nationalist propaganda during the (first) Cold War.
Lastly, what the US is now seeing in terms of societal unrest, is that you've now got a far-right president again — similar to how it was under Bush Jr., but with (so far) less beating on the war drum — and that therefore the relatively peaceful middle ground between Republicans and Democrats is starting to disappear because of the extreme polarization. The only ones who are happy with that situation are the far-right bigots themselves, like Alex Jones, while the rest of your country is in turmoil.
Just my two Eurocents, for whatever they're worth. It's all I can spare at the moment, because my government is trying very hard to mimic yours.
