This has so completely disappeared from discourse over the past four years. I remember when it used to be that "building the wall" was stupid at best and bigoted at worst. But now, it's all, "Of course we agree that we need a strong border, but we're the ones who will actually do it, Trump's all talk."
It's always the Republicans that get to set which values and goals the country persues, while the Democrats just run on pragmatism and efficiency. It's like they're allergic to making moral claims.
Animals fight and kill eachother over territorial disputes regularly.
Humans have done this since the beginning of human society. Technology arguably only exists as an extension of being able to kill other people more effectively. Politics is just a mechanism for directing and organizing the effectiveness of modern human society in order to best defend it's values and resources.
TL;DR given the ability to influence and control things, humans (or animals) will take the opportunity to do so. Everything around you is just an extension of this ability.
Oh, oh no, no no no no no, No. this isn’t a one party system, this is something far worse, this is what comes exactly right before a one party system. That is a two radicalized polarized adversarial party system. One must go but neither will leave willingly, there is more concentration of money and power in these two parties than possibly any other group on earth and maybe through out all history, make no mistake the only thing that will hold the country back from civil war is the Bomb, and that is only a maybe.
We might not quite be that bad yet but all the peaces are in place and adversarial moves are already being made.
