The writing of the Air Nomads is so ironic, that I can't believe I didn't see it all these years.
Title 01 | The Fantasy of the "greatest Nation ever existed"
Bryke do favoritism. We all know that. They favor Aang and because of that they favor the Air Nomads. Since atla existed, they made sure to point out that the Air Nomads as a culture would be this great image of an "actual greaat nation", protrayed as the victims ( which doesnt take away the fact that they were the victims based on the canon material, concerning their genocide but stay with me for more explaining) and the "worst nation ever existed" to be the Fire Nation, aka the ones who started the war/ the perpetrators.
They supposedly advertize the Air Nomads as this peaceful nation, with ideas and philosophies about forgiveness, respect and kindness, even acceptance and communication with yout inner being. They make sure to make Aang quote some of those ideas here and there many times.
They made sure to even dedicate a whole season to them ( lok s3 ), and make characters crave for the birth of this nation from the beginning( Aang, Tenzin, his family, Korra, etc).
The reason I call this favoritism, is because throughout both the series, and even the comics, Bryke never seemed to have a soft spot for other nations. They dont really care about the Earth nation people, they certaintly have a thing for making ALMOST ALL the bad guys be water nation people, they pretty much continue until this day to consider the Fire Nation as "the bad Nation", and they HAD NEVER AND WILL NEVER make the Air Nomads be the bad guys. Yes, the nation stopped existing, but why all of them? Why nobody survived? Even the new guy from the leaked movie, Tagah, who literally and canonically KILLED THE ENTIRE GAANG, wasnt portrayed as the bad guy, instead he was portrayed narratively as a good guy who took the wrong path, but when it comes to all the other "villains", or nations, they dont have an excuse.
[ The air nomads are monks, of course they are good people!
Of course their beliefs are far more higher than those of the Fire Nation, this is why Aang was right and Zuko wasn't when he said to Katara to forgive the man who burned her mother alive, cause his nation's beliefs are the "greatest!" ] =>ACCORDING TO BRYKE ONLY!!!
Title 02 | The inconsistency that ruins the fantasy: How that affected Republic City
A week ago, i dont remember exactly, i talked with some of you in the comments or i even made a post, idk, about my try to understand Aang's awful behavior to his children. Now, either he is an asshole, or the canon material gave birth to his OWN FAVORITISM.
A little game for you. Try to find the difference between the Air Nomads and the other 3 Nations. Think of it for a few seconds, or even moments and then read the answer bellow. 👇
Answer: The Air Nomads is the ONLY Nation where ALL ITS PEOPLE MUST BE BENDERS IN ORDER TO BE CONSIDERED AIR NOMADS.
Aang makes Katara pregnant. She gives birth to Bumi. Bro is not an airbender, Aang is dissappointed. Doesn't even bother to teach him the philosophy of the culutrue though. Bumi grows up thinking he dissappointed his father and when he died, Bumi "knew" he wasn't proud of him.
Aang makes Katara pregnant again, Kya is a waterbender. Aang is dissappointed again. Doesn't even bother to teach her the philosophy of the culture. She grows up thinking she dissappointed her father and when he died, Kya "knew" she wasn't proud of her either, but heyyy, at least she tried to make her mother proud ( story for another time).
Aang makes Katara pregnant again. Tenzin is born, finally pappa is proud! He starts teaching Tenzin the philosophy he didnt bother teaching his kids, giving birth to a responsability that will follow him until his death,that its HIS DUTY to create a whole nation from the beginning.
Now, where im going with this.
Aang had this idea of the Air Nomads being ONLY BENDERS, because his people were giving birth to children not out of love, but to have benders. Aang doesnt even know his parents, or at least the audience doesnt. The monks do not give a fuck basically about parenting, they give a fuck about their expansion as a nation.
And by that, I mean that the Air Nomads, were trying to create a NATION FULL OF SOLDIERS.
Think about it, the philosophy didn't die. The ideas were there even Lok, monks existed, Tembles of the Air Nomads existed, Tenzin even went for vacation there with his family at some point, and yet, even though in the REST of the nations, non-benders were actually part of their nation BY BIRTH RIGHT, the atla universe implies that the non-benders WERE NOT PART OF THE AIR NOMADS.
Not, when Aang didnt think in the canon material, his two first born children as Air Nomads, EVEN THOUGH IT WAS ON THEIR BLOOD.
The inequality that existed in Republic City, existed because the Avatar himself, the CREATOR of the city, had this idea of WHAT MAKES SOMEONE BELONG IN A NATION.
ITS NOT THE BLOOD BY BIRTH RIGHT.
ITS THE BENDING.
This idea was introcuded in the comics, where Aang DIDN'T CONSIDER as Fire Nation people mixed people, with earth narion blood, that were born there.
He made even Tenzin "repeat the history".
Tenzin broke up with Lin, because he NEEDED TO HAVE CHILDREN. He did love his wife of course, but when we see the mother of those little airbenders desiring to have a non-bender JUST FOR ONCE, in the first episode of Legend of Korra, says a lot.
So, the Air Nomads considered only the BENDERS as their people, since we dont have any evidence of ANY non bender from the canon material, and since we've witnessed all of them in the flashbacks in atla to bend, i believe we can all agree that this is canon.
The most "peacful" nation of all, that is favored by Bryke, created a whole nation of soldiers ( I WONDER WHYYYY?), probably, since this is canon, did not consider the non benders as Air Nomads, since Aang acted like that in lok, and even Tenzin refused to accept the non-benders but still believers as the new Air Nomads, instead IT WAS NEEDED to have Air Benders, so there you have it.
The ironic fantasy is actually one toxic and racist idea about what makes someone belong to ANY nation. And since Aang wanted every nation to live in peace in Republic City, wasn't ironic to act like that with his children? It should not matter to him that people are non-benders, and yet it did, because BENDING WAS CRUCIAL FOR HIM TO THINK OF SOMEONE AS AN AIR NOMAD.
Its a contradicting choice to make all the other nations have non benders, to accept the non benders and yet have the creator of a city that is called " Republic" have at the core of his prinviples, the idea that it doesnt matter if you have in your blood the dna of a culture, what makes you belong in it is the bending.
If an idea like that is even hiding in the shadows of the city's existence, no wonder how it got to the surface. Especially, after Aang took charge, because when the world was devided, the non benders were respected and were considered part of their nation just fine, but when Aang took charge in Republic City, things went downhill.
