Native Americans have lived in these places for thousands of years. Much longer than cars, industry, datacenters and their resulting climate change. I'd fault the latter for this situation, not the victims.
Native Americans not only lived there for thousands of years, they had been doing fire mitigation for most of that time, very effectively as I understand it.
Then we white people moved in, scorned their deep-rooted knowledge, and murdered most of them, so even without climate change, we'd be likely to see worse fires than a few hundred years ago.
I also don't think its at all offensive to suggest someone should move. Native American tribes moved about the continent seasonally at a minimum. Most of our college students are asked to move to pursue opportunity, with the expectation that they'll be moving again for the same reason. Fleeing dangerous areas and flocking to safe ones happens in all kinds of populations for all kinds of reasons, and if this is the first time your family has been displaced across multiple generations of ties to what have been some of the most desireable locations avaliable it seems like you've been an outlier in the best way for generations.
