I mean... yeah he's right but he's made too long of a history for himself of being a fucking douche for me to really be able to acknowledge that without pulling a "broken clocks" routine. And that's really his own fault.
You're right he's not a Fash, but you really can't make that argument to most people now because he's acted like enough of an ass that it doesn't matter, he's in the "asshole zone". He's beyond the point that injecting nuance to criticisms of him is really worth it. He's smart sometimes but otherwise he's far to far gone.
There were only 4 tribes of them and each tribe occupied a temple complex the size of a small town so yeah I think their population was pretty small. They seemed to mostly eat fruit pies to I imagine they gathered fruit from tree (either that they tended or wild trees) and traded with other nations for cereals and other staple foods.
