While saying that indigenous people are inherently more connected to nature is at best iffy however I think the point the comic was trying to make is that on a general basis indigenous are (or were depending on how much of their culture and history has been destroyed) more knowledgeable of the lands that they have been inhabiting. More specifically compared to the colonisers that invaded their land.

I see this as racist rhetoric, and I think the point of the comic was to be divisive. It's not that I don't understand the reasoning, it's that I'm looking at it from a step back.

Like if I made an anti-crime meme, and tossed in that blackmen are convicted, and charged with more crimes, the racism would be a lot more apparent because it's promoting negative bias towards blacks.

But this shit isn't any less racist, it's just more palatable.
