I don't think it's accurate to use the word genocide today (common and garden "racism", "ignorance" and "greed" all work). However, I think it could be argued that the residential school system was intentionally and systemically structured around "cultural genocide".
Unconscious to a mass of people that were informed in such a way that they were insensitive to what was happening?
There is a large force of people that would say there is no such thing as an unconscious psyche ... that would pose a dark and mysterious item in the domain of folks claiming to know God and everything!
I claim to be uncertain to such things as according to the 3rd item in mystical attributes! There are those that are determined such an attribute is wrong in a determinate world. I still say we have a lot to learn about indeterminate matter ... dark stuff is mostly unseen!

Is an indeterminate soul something difficult to grasp thus accounting for the stoned lady at the wall as a psychic being that put the mysterious hand on the wall as a carved myth?
Was V' Noos carved in stone ... accounting for the deeper sense ...
