Here's the synopsis the train [wreck] of thought, for those too lazy to read the article:
- Captain America is the quintessential representation of American idealism, in terms of moral compass and judgement
- The author lauds this expression in the previous films, noting Captain America's loyalty, solid judgement, and [importantly] unequivocal stance that too much government power/control was ripe for abuse, and thus needed to be countered by the people
- There is praise for Captain America's valuing equality, protecting people from the machinations of powerful entities, and insisting that the government be transparent and accountable to the people, not the other way around
- ... and then, in a monumental 180 of blind cognitive dissonance...
- Baffled disappointment that Captain America fails to embrace total governmental control of all powerful individuals
- Equating the definitive moral correctness that Captain America actually inhabits, both figuratively and literally, as libertarianism, about which the author is dismayed
As it not atypical with presumably well-educated people, the observations themselves are perfectly valid. For example, Captain America's political ideology, such as it is, could certainly be described a libertarian: favoring less abusive government, more government transparency and accountability, and individual freedom. This was fairly conclusively established in The Winter Soldier, and although the author seems to acknowledge each individual point, for some reason the sum total implication escapes her.
If I can speculate for a moment, I believe I also understand the root of the problem (causing the mind boggling cognitive dissonance). See, liberals tend to assume that [the will of the] government and [the will of the] people are the same, and that government is an extension of the people. This is obviously inaccurate, both in the real world and in the MCU (which largely mirrors the real world in this sense). In the real world, government is controlled by powerful people and institutions, seeks to ever increase its own power and control at the expense of individual freedom, and makes a mockery of the values which Captain America stands for (making it natural and obvious that he would oppose the government control in the MCU, as he does).
In liberal fantasy world, reality is ignored, and the pinnacle of perfect society is complete government control of every aspect of people's lives. Thusly (following the mindset), Captain America's rejection of complete government control is disappointing, as it is a betrayal of the liberal ideal. But here's the thing: the liberal ideal is a betrayal of American idealism itself, as hammered home eloquently and repeatedly by the Captain America movies themselves. What's really amazing, though, is the liberal author's complete inability to grasp the obvious: her political ideology is so pervasive in her thinking that she seemingly cannot even comprehend her absurd her conclusions are.
It really just goes to prove the point that having a strong mental political indoctrination can blind you to acceptance of facts, even if they are obvious. It's also a good object lesson on why its profoundly dangerous to have people in power who are political zealots (of any "side").
