I understand how this person's responses are frustrating to you, but educating us is no one else's responsibility, and people are allowed to assert that you're wrong. You can choose how to engage with such people, but I mean if you haven't confirmed that you understand the difference between the two types of agreements (I also don't know, no shame there) then instead of insisting that it is someone else's responsibility to educate you, do some legwork on your own.
Or don't, maybe they're just an asshole. But don't demand people do unpaid labour on your behalf.
I don't think you meant it this way, but I feel a bit uncomfortable that your comment plays into the "corrupt First Nations" narrative.
Of course, some First Nations have misspent funds sometimes, but so do Doug Ford and Danielle Smith. Ontario and Alberta are just rich enough to absorb mistake after mistake. Do Ontarians need oversight or can they govern themselves? Meanwhile, any mistake by First nations groups are scrutinized as moral failings, and stereotyped onto the whole racial group.
Check my top-level comment, hopefully that's a bit more constructive. Please see my other replies to as I am def interested in learning and getting a better unbiased understanding of what is up in the areas I asked about ;)
