Despite all those themes, the Taxxons death is never questioned because they are monstrous.
Taxxons get a horrifying last minute reveal that the whole species is headfucked. But there's not enough series left to explore that.
By not having any Taxxon characters, by making the leader of the Taxxon Rebellion an Andalite, the work is complicit in their erasure.
Taxxons? I feel pitty for them I guess, but they're gross and scary and horrible.
If they're "violent", "savages", "unsavable", "pitiable", "better off dead", "subhuman/(subsentient)", "wrong", "they volunteered". You might convince yourself lo let a lot of bad happen to people.
"Even the barbaric Taxxons in their own way" "Who can say what Taxxons think."
The Hork-Bajir reveal, gives you your noble savage stereotype, and problematic as it may be, makes you question your perception of them as big dumb scary razor lizards, to *friendly* still dumb but lovable reptilian salad shooters.
Because most people don't get past that knee-jerk reaction on their own. The books would have had to put in the work, put in the word count to get readers to sympathize w Taxxons
But it doesn't, so most readers that even made it to the last like 4 books in series, didn't stop to think about Taxxons in their own.
The fate of the Taxxons is unclear. We don't know if they have a world to return to. We don't how many generation Taxxons have been servants of the Yeerks.
Whatever. I don't need canon answers to that.
The only problem with this mentioned by the books is poaching...
I 100% understand, that many Taxxons would take that, as many cronically ill people might happily become a literal eagle for the rest of their life if it would relieve them of their illness. But many wouldn't. Especially at that high personal cost.
We're not told
The Yeerks do mull it over, several times, in previous books. They get all philosophical about it.
Taxxons did not have a central society outside the Yeerk empire
If all free Taxxons go snakxtinct, and any leftover Taxxons are still under whatever still passes as Yeerk rule... Do they survive as a species?
And I don't need to know. And its fine if they don't. It's fitting.
And to be fair, I do think she mentioned in interviews somewhere that they coulda/shoulda/woulda done more with Taxxons if not for whatever constraints had come up
There IS just enough there in for me to overanalyze and point out. It's just never picked up so it feels like something's missing.
Which there is: The non-existent Taxxon Chronicles
