my two cents:
1: people have been "told it all their life". i'm going to use the word indoctrinated in this somewhere, so it might as well be here.
aside from pure indoctrination, there's the simple lack of a second opinion: people don't know that it's possible to NOT follow the law. i barely even see police officers, and i've been exposed to things like anarchism, so the law is a more abstract concept to me, but there are some people who think it's just how the world works: "you do thing A, police show up and take you to court B and jail cell C" and they're thinking "yep, always been that way, always will be that way". they make it an inherent quality of the world and proceed to
quote the law as if it were physics.
2: people have nothing else to cling to. if someone doesn't feel there's any rhyme or reason to the world, they can cop out and say "the government will tell me how to act! then everything will have meaning again!"
3: fear of the most terrifying bugaboo of the day: the dreaded [communist | anarchist | socialist | nazi | terrorist | criminal | insane person | anyone who is waving a gun in my general direction but doesn't have a little flag stitched to their military garb, because that makes it alright to have a gun to point at me]
the problem i have with these people is that if everyone is so terrifying, especially if people are "naturally [greedy | violent | ignorant | made it their life goal to kill me, specifically]", how could you possibly trust a person you haven't met from across a 3,000-4,000 Km country? having common heritage obviously doesn't work forever, since we're all the same species, so what could it be? is it that we all watch the same TV, because if so why aren't we moving TVs out ASAP? is it that the [desert | tundra |
] makes them naturally hate you, in which case why don't we just nuke them and get it over with? the only thing that isn't a quick answer like that is that everyone in the military is afraid of everyone else in the military, in which case they should just talk it out and create a dictatorship or something, or a mercenary who joined up with the largest and best paying group!
the most baffling thing is that apparently the army makes you swear an oath to the constitution, so either everyone in the military are blatantly lying about loyalty, or people can actually believe in ideologies, and if people can have opinions, the only enemy is irrationality because everyone else can either be proven wrong or shown that we don't know how do decide.
