There’s a tendency to treat indigenous people in the Americas as almost always either in the past, nonexistent or imaginary. That actually not only robs them of their humanity and actuality, but also robs others of their reality as well (both the good and bad). Perhaps the tendency to treat indigenous people as oftentimes imaginary or nonexistent does contribute to both attempts at getting rid of them and also ignoring whatever problems they face in the real world, which’s why it can be this hard to bother empathising with them in any way. One such problem includes the persistence of colonialism and cultural assimilation, that’s the pressure to give up their indigenous cultures to better blend in with white people in this case.
While not unique to them in the Americas, it’s a very thorny problem as they got there first. Hence that’s why they’re called Native Americans in America and First Nations in Canada, with similar words likely showing up in the rest of the Americas. To make matters worse, some white people will even appropriate or co-opt indigenous customs, costumes and beliefs to make them sound more indigenous or more special than they really are. When it comes to totem animals, these are oftentimes hereditary passed down from parent to child either patrilineal or matrilineal. Among the Akans of Ghana and Cote d’Ivoire, various clans have a totem animal. Some families would be associated with the dog totem, which represents adroitness and thus cunning.
Some would have the leopard totem, which is associated with aggression. Should you marry an Akan woman, since Akan totems are passed down matrilineally it’s going to be fat chance since the person who will inherit the totem animal is the child, not the spouse who wishes to live vicariously through them. This is likely the same with some indigenous communities that have those, well at least essentially or practically so. No matter how many times a white person tries to claim a totem animal or something similar, if these animals don’t have the same meaning or significance as they do in some non-Western cultures it wouldn’t just come off as cultural appropriation.
It would also be preposterous, especially if (certain) animals didn’t play such a big role in some Western cultures to begin with. Well some cultures in general so to speak. The tendency to treat Native Americans and their ilk as oftentimes nonexistent or a mere fashion has made it this easy to appropriate their cultures and beliefs, though this could be applied to other people of colour (in the West and the like) to an extent as well. It’s also that easy to gloss over their rights and suffering, so there really needs more awareness of them as people. It already is to some extent among some people, but more work needs to be done to minimise such problems.
