I don't know enough to dispute the doctrine/dogma points you've brought up.

All I know is if someone asks me to use a different term when referring to them, I usually oblige out of respect. That goes for transgender people that want me to use different pronouns/names, religious people that want me to use different terms, etc. If someone says "please don't refer to people of my tribe as 'Native Americans', we prefer the term 'Cherokees', I'm not going to start debating them and be like "well, your leaders last decade wanted 'Native American' so I refuse to call you what you currently prefer". Intentionally ignoring a request like that is incredibly disrespectful and rude, in my opinion.
