Where was the part where he said that Obama wanted open borders?
While Obama(and Hillary) give lip service to Marxist determinism, which includes eventual dissolution of national borders, neither is or ever has been free to just do whatever they want. And while they have done astonishing feats of disregarding law and principles of every kind, it does not mean they are hypocrites. They are hirelings, not revolutionaries. They actually have no principles or beliefs that matter.
The point is, they are demonstrating the power of their political benefactors/managers.... the few, the proud, the arrogant... the UN-Americans...… those few real powerful inner circles..... who are demonstrating their power, for show.
Their methods align quite well with the philosophical ideas of Napoleon and many other historical dictators across the ages.... they are best described by the idea, the philosophical claim, of "arrogance of power". Meaning, when you have the power you are above the law, you are beyond criticism, beyond the reach of reason. You simply display the ability to do what you want, without accountability and without justification.
AOC is not her own person, really. She was found, and financed, by The Young Turks..... by very wealthy backers of the Young Turks, who wish to use socialism to degrade the American principles of liberty. The Democratic Party is in turmoil, but it is only a quarrel between contestant look-a-likes vying for the leadership of the "Democratic Socialists", really the communiast (fake progressives) who think this is their hour.
Since this is not any kind of ideological or principled "cause", don't look for consistency or beliefs or any kind of reason, or any kind of vision for the future. This is simply a contest for raw, unaccountable, unchallengeable POWER over the human destiny. Just who wins..... does not matter. What does matter is that it is a "final solution" to the problem of limited governance for the fascists of our day.
And aren't ya'll just proud to be the chumps who help that happen.
