I've seen this comment a few times now and I'm pretty conflicted, especially as I'm the white coloniser and can't speak for Māori.
I think it's important to point out that Māori have worked incredibly hard to reclaim and preserve their language, culture and this particular Haka seems to have resonated with a lot of Māori. It's not a land acknowledgement from a blackrock CEO, or the Democrats kneeling for George Floyd.
But.. The cynic in me says: It is performative. As are all parliamentary speeches and rituals. As is the bill itself which is right-wing virtue signalling. The lib in me: It has brought a lot of attention to the bill, and made it clear to "well meaning anglos" that it's fucked up. The materialist in me: The treaty barely impacts capital's ability to make profit, so overturning it seems quite far down the list (for now) for the local borg.
Yeah referencing existing flag colours with the shape referencing mountains & marae wharenui
