Native Peoples

Native people are often in a relatively unique situation when it comes to going vegan, and while it can vary from region to region, generally speaking it is significantly more difficult for them due to their marginalized status and reliance on subsistence hunting/fishing for survival, as well as less pressing from a moral perspective to encourage them to do so because the source of their animal products is usually both more sustainable and less cruel than typical animal agriculture: in sum, it makes promoting veganism to native populations a poor bargain in terms of effective activism.

You'll have a hard time getting very far or convincing many people, and even if you do succeed the payoff in terms of animal suffering prevented for success will be much smaller than having convinced somebody from the mainstream/dominant culture to go vegan. So in short: please don't waste your precious activist time on trying to convince people for whom it may be nearly impossible to go vegan. Focus on the low hanging fruit from within mainstream society where going vegan is much easier and more productive.
