Ok so random 40k theory that came to me while on the shitter.
You know how the Orks have their own unique gestalt psychic WAAAGH wavelength that while linked to muh Warp is effectively (
if not completely) unhackable by Chaos and renders the average Ork surprisingly resistant to Chaos corruption? Well I was listening to a mixed lore/theory slop playist and it occurred to me, what if that shit is exactly what the Tau have going for them in their own gayass space commie way?
Basically the Tau Ethereals have since the getgo been dangled as maybe/maybe not psykers who effectively mind control the rest of the species and somehow "inspired" extremely rapid advancements in tech and science by their mere presence, however the lore repeats over and over again that they don't give off any signals of actually being psykers by Human or Eldar standards.
So my little shitter-birthed theory is that by random chance or Eldar/Necron/Zoat/Jokaero design they have their own low level psychic gestalt harnessed by the Ethereal subspecies much like Weirdboyz, that is more of a general "everyone work together for the greater good, you will own nothing and be happy, oh yeah and don't ask questions" buff than the swole gains and specific "go on a giant fucking murder spree lol" vibes of WAAAGH, which is what has allowed them to catch up to the rest of the setting so fast while also not being corrupted or kerbstomped by Warp shit as quickly and painfully as one might expect a naive zero psychic species.
Plus this would actually fucking explain the fact that a straight up Tau goddess exists in the Warp that is seemingly capable of kicking Chaos in the dick and offering tangible protection to the Tau who get stranded there, rather than the handwave of it being because of the relatively tiny number of Tau aligned humans randomly sharting her into existence by praying to the Greater Good for a couple centuries tops. Think of it as a mix between Gork/Mork and an Imperial Living Saint.
Speaking of which, I am pretty fuckin sure that the Imperial cult and Emprah worship is humanity's nascent version of this hypothetical "racial psychic gestalt" and that the Sororitas are straight up the closest shit humanity in the setting has to Orks given how tangibly they manifest it for killing shit on the regular.
And fuck it, let's beat a dead horse. I never liked the "Imperium are bad guys and fascists" bullshit. Yeah, it's a fun hypothetical or one off interpretation. But it really gets away from the spirit of the faction imo.
I have probably said it before, but frankly for me the setting works best when you look at it from the mindset of "each faction is insane/evil in their own unique way....and each faction has
extremely fucking good reason to be like this and has learned from bitter experience not to rock the boat"
Sure the Imperium is an authoritarian and superstitious shithole, but given just how fucked the universe is and how many nightmare hell wars they are fighting in any given microsecond against external threats, internal threats, and an ever growing ensemble of extra dimensional lovecraftian fuckers, their policies of fanatically squeezing every last drop of resource from the masses while enforcing ultra draconian tyranny and allowing all manner of lower level inefficiencies and corruptions to fester and having an extreme "kill everything in sight first, then kill the nigger who asks questions later" attitude are by far lesser evils compared to risking shit falling apart, given just what kind of monsters would have free reign to enact a figurative and/or literal rape train on every single human world should the Imperium be seriously weakened through the front lines breaking or through internal division and mutiny or even through some random warp/xenos corruption metastasizing because Inquisitor Obama Shylock Trudeau decided it would be a little excessive to phosphex bomb the local orphanage after Death Guard Captain Poo'gor the Stinky laid a sentient turd on its front doorstep.
EDIT:
Nigga how could you leave out the most important fact?
The turbo faggot wrote evil hatemonger "Sarkon Aggad" to be effortlessly slaughtered by a stunningly brave and sexy they/them troon.
