But I think the methods by which they're being manipulated are quite alike, and ultimately forced to side with the current tribal figurehead simply because it's not the other tribe's figurehead, even if there are many, and legitimate, contentions.
When one chess player chooses to suddenly say that a pawn can move 3 spaces, and you insist on calling a ref to call out cheating, I don't think it's just "two tribes" anymore. You agreed on the rules of engagment at the beginning of the match and one side is objectively breaking them. Saying post haste that "well maybe a pawn should move 3 spaces" does not negate what you agreed upon.
That's why it's tiring to head the "but you're being manipulated" argument. Being manipulated by the very rules of your government is different from a bunch of war mongerers, billionaires, and corrupt politicians continually ignoring the rules and saying "no it's okay".
They operate under the "might is right" mentality, and by getting away with it prove in a sick and contorted way that the rules of social order aren't universal.
