So I just finally caught up after a long period of shit internet, skimmed the thread so I'm probably repeating what's already been said, but this is what I got:
Spoiler:
This show as it turns out is deliberately and quite blatantly making fun of and criticizing organized religion and fanatism and mormons.
I mean fucking look, since the start they're talking of the original sin, Raigyou is basically a religious nutjob a la Joseph Smith/Fred Phelps/Pick Your Maniac, who thinks she herself alone has seen the Truth of The World, and she'll work through any means necessary to impose her perceived salvation(fucking sentient clothes) on everyone. Hell, she's even crucified by her daughter, if that's not a direct poke on christianism nothing is. Also salvation comes from freaking aliens from space and there's an alien spaceship of salvation, mormons I tell ya.
And then there's Ryuuko and Satsuki finally mutually accepting that the reality of the world is beyond their immediate comprehension, as per demonstrated by the lunatics that follow them, and it's okay to not know everything. That's also pretty obviously to me a praise to skepticism and only saying you know things when you know things, as opposed to taking a spoonfed story as the all truth as per religious indocrination.
I know, I'm spouting edgy as fuck shit here, but it's fun as hell
Senketsu is mai goddamn husbando btw. He even goes full tsundere. I'm mad gay for a piece of clothing.
