I gotta be honest but

AC: :33 < and i dont know anything about classes or bases or blood color, it doesn't matter!
AC: :33 < what does gr33n blood even mean! it doesnt mean anything to me and it shouldnt mean anything to anyone else!

reads as extremely, appropriately naive of Nepeta being someone who doesn't personally have to deal with what the castes mean/imply. She wants to play her roleplaying games, not think about politics. Which also means not being explicitly anti-caste, either. Lowkey the "weed smoking catgirl" archetype is entirely apt to be not really thinking about implicit biases or w/e. I don't think anyone here is saying that like, Nepeta is a bad person, it's just a small detail that's part of a larger trend. It is funny that most of the defense of Nepeta (and i did laugh at the flip of Nepeta being a saint for putting up with Vriska at all) is reading quite heavily into assumptions of her psyche and justifications that aren't really textual or anything we actually know. We could easily read completely the other direction if we wanted to, but it's all entirely besides the point. Whether Nepeta is or isn't Caste Woke is irrelevant to Victoria's point and the larger trends that she was discussing.
