I'm not even a hardcore anti AI person. I think LLMs are neat as a technology and I enjoy running a small open source model locally on my computer!!! But I truly feel like a guy who's into origami suddenly watching society decide they're gonna make every building's load bearing wall out of origami paper. Like that's not what it's for 😭

I cannot tolerate interacting with USA supporters.

Blue maga pisses me off more than red, because red voters are too stupidly brainwashed to be blamed for much other than shitting the bed. They're pathetic, but violent. Their danger isn't coming from them being too bright or clever.

When liberals shit the bed, it's on purpose & with all the data about bed shitting fully at their fingertips. They're deeply fucking dangerous. They praise the FBI every day, now. They demand cops, they insist on responsible surrender to and complicity with rapacious neoliberalism. They are worse. They're the trustees of the prison and they are proud of it. They are more than capable of cleverly serving Trump up as their excuse for No End of massacre, pillage, theft, pure malice.

Liberals can, should, and will fuck all the way off, forever.

May I ask, did you get around to writing that essay about ga-matoran in Metru Nui and their connection to the Great Temple? Not expecting anything! Just curious!

Oh, I think I wrote a bullet-pointed list on ga-matoran and their connection to the Great Temple, specifically looking at how it affects their concept of gender here, but I never wrote anything long-hand.

If a quick rundown is what you're looking for, follow that link. If you do enjoy long(ish), rambling essays from someone making far too extensive headcanons for fictional worlds, read on.

So. Ga-Metru. The metru of the ga, the metru specifically for the ga, that metru. Now, I could launch straight into the impact of Ga-Metru being Mata Nui-favoured... but this is my essay, so I'm gonna roll this a bit further back and delve into a possible reason of why Ga-Metru is favoured.

Because I have a personal headcanon that Ga-Metru's favoured status was very much a byproduct of the natural resources.

Look at it this way: You need to build a protodermis purification facility on Metru Nui. You've already built the forges and furnaces; now you need to be able to source the building material for these smithies. So you need somewhere with a lot of liquid protodermis readily at hand - somewhere, for example, like Ga-Metru.

And then, because you probably shouldn't put all your important masks in a place full of burny, melty fire, you store your kanohi mask here (instead of Ta-Metru) as the other major building in this budding metru.

So, ta-da, you now have your second major site in Metru Nui, and over time that becomes Ga-Metru, home to the Ga-Matoran. Second-eldest metru, not out of any holy significance, but because it provided an important resource.

Time passes, and your purification/storage facility becomes a place of spiritual importance. I mean, it makes sense. It's an old, vital building, storing items of power, and isn't the hot, noisy space of Ta-Metru, plus the act of purifying carries a kind of holiness to it.

So, the next logical train of thought: if Ga-Metru is home to the temple of your god, then - obviously - god must like this metru best.

Next, next logical train of thought: if Ga-Metru is the favoured metru, then those who live there must be Mata Nui's favoured matorans. Or, at least, they are spiritually closer to Mata Nui, living basically on the doorstep of your connection to him.

By this point, matoran have certainly been granted sentience, and with that comes all the messy irrationality of thinking for yourself. What a lot of religions like to do is recognise those singled out, spiritually, with a title. Father. Reverend. Back in the medieval era, catholic priests were called "Sir" the same way a knight was.

Regardless, the point is: you need a name or a title to recognise that Ga-Matoran are different. And (headcanon going strong here) because Matoran weren't programmed with a sense of gender, they only really have "he/him" for daily use, with "brother" as a title of respect.

So language does what it always does in these circumstances - it adapts. Except, well, the Matoran may not have a concept of gender, but the Great Beings who created them did. So, somewhere in that pesky programming and superfluous data, there's a not-memory of "sister" being an equivalent title to "brother" - they don't understand how it relates to gender, they just know it feels right. And with "sister" comes the pronouns "she/her" so suddenly you have a whole metru with their own special pronouns and titles.

And, ta-da! Matorans have now accidentally ungendered gendered pronouns.

I also think it adds an interesting sense of irony for any (head)canons that Ga-Matorans consider themselves above or better than other Matorans (because then their importance is built on a coincidence, rather than actual Mata Nui favour) but that's for another day - or for other people to take a crack at, if they'd like. (I know I've certainly seen some interesting posts about Ga-Matoran self-importance!)

I personally was just fascinated by the fact that the "female" Matoran are the "holy" Matoran, despite gender being nonexistant, and examining one possible reason for Ga-Metru gaining its favoured reputation. (What can I say? I love clawing my way into the cracks of existing world-building.) Feel free to agree, disagree, whatever, but these are my personal headcanons and I hope people enjoyed reading about them!
