"Patriotic duty" is really just the nationalist and (mostly) "right wing" equivalent of "the greater good". It's just another form of collectivist bullshit.

>It's your patriotic duty to vote in fake elections
>It's your patriotic duty to pay your taxes
>It's your patriotic duty to snitch on those who don't pay their taxes or cheat on them
>It's your patriotic duty to be drafted and fight in bankster wars
