One that doesn't take its own myths seriously compared to one that does? You'd be hard pressed to find a neopagan that thinks Final Fantasy is offensive to their beliefs, for a very loose example. With Wendigos, I hear this on the regular, and I'm in no place to decide if they're being reasonable or not, I'm not Indigenous.
On names, that's the entire problem of cultural appropriation. Back then, it was a normal roman and/or catholicization method to act like all the pagan gods are just really normal humans or sly demons to legitimize dropping those beliefs. Several US Indigenous populations are car brands according to google. A certain g slur got used for wandering performer aesthetic in a LOT of places and a lot of people, including me for a time, thought it was the right way to refer to Roma (it wasn't). And now, Wendigo is spooky skull deer thingy. Diluting a culture that would like people to, please, do proper depictions of their beliefs or not do it at all, is pretty bad.
"They did it before and it was okay" does not justify doing it now, I already said this in a previous post. Do. Better.
