I'm not sure if you meant to use "salient" here (as in you're using the word incorrectly), but I definitely wasn't trying make my writing that.
I'm also not sure about what else is said here either. Plenty of people behave immorally despite having role models; and I'd hardly say good people are in short supply despite how doomers insist the world is right now. I'd also caution against resorting to individualist explanations for this as well, and I was trying to discourage that by emphasizing the relationality between individuals and systems.
This is also by no means nothing even remotely new, but the specific form of normativity that people engage with this from did indeed emerge from modern European colonialism, and therefore Christianized notions of moral purity. But by, "nowadays" I reckon you're not positioning this as a centuries-long development.
And then, "holding us back," itself casts a normative construction of how things ought to be, which is exactly what I've cautioned against. I'd hardly imagine your understanding of a collective addresses decolonialism in a way that doesn't subordinate groups or values that are "holding us back," from some idealized, "proper" state that thing should be in by now.
