Heh... So if I understood it right, our Lady Baby grew up to be a colonizer who's going to...

This cannot be colonization because colonizing means invading a culture and imposing your own. They're part of the same society but it just does not belong to the same class. You can speak of borrowing code because at first glance this is what she seeks to make the popular culture value among the aristocracy so that this class could resists the authoritarian and liberticidal excesses of the temple. She does not appropriate their culture since they are part of the same society. She want just to borrow the communer class codes ╮(￣▽￣)╭

yea thats kinda messed up and unexpected from the plot

I said colonizer cause it felt wrong to just say white people, and I don't know if there is a term for what she's doing. I understand your point about it not being colonization, cause yes, there is no colonization is this story.
I can't, however, agree with you about appropriation. White North Americans, for example, appropriated Jazz and Hip Hop from the Black Community and they are still in the "same society".
Even this "same society" can be argued. Lippe grew up in high society, she has completely different life experiences and culture (she herself used this word) from the community she's seeking to appropriate, so how can we say they are equal and are part of a single unity?
The fact is, she's gonna steal their culture and spread it in high society. High society is gonna absorb, develop and claim it as theirs. If she succeds she's gonna be remembered as a pioneer, while the community she stole from is gonna be undervalued (if not completely ignored) by the mainstream.

Also, I'm sorry, I didn't really understand what you said about code, cause code for me would mean language, that's why I'm not commenting about.

Yeah, it was a total 180. I thought she was gonna fight the church with business, magic and/or her status as a noble, I wasn't expeting none of that about singing and cultural appropriation

I wanna disclaim that I'm Brazilian, and not North American so I shouldn't have mentioned about Jazz and Hip Hop, cause I don't know enough about it. So if what I said is wrong, I'm sorry.

I do stand about my belief that Lippe is trying to appropriate that community's culture, tho.

Don't worry, I know what you mean. I am black so issues related to cultural appropriation etc. I know. What I mean is that it is a uniformly white society so it does what is called "a cultural code loan", basically rich people do it regularly. They are able to go to the opera then go to a rap concert in the working-class neighborhoods. Yes, I don't condone the practice, but I just wanted to use the right words. After I hope that the author will not let this story go in this direction, but on the face of the situation, only the aristocracy can prevent the gain of power of the temple.

Oh, I understand what you mean better now, thank you for explaining it!
About the shift in the story, yeah, I agree with you. But at the same time, it feels like she chose to fight swords with a napkin. Wasn't the church supposed to start moving soon? Will she even have enough time (and influence) to normalize folk songs in high society before the church starts "devouring" everything?

I hope so ┗( T﹏T )┛ But you're right, I hope it will still strengthen because its strategy remains wobbly (╯°Д °)╯╧╧
