I’m going to answer this in good faith.

Not wanting to cause someone else discomfort or pain, is not about being “offended” on their behalf. We need to get away from this “offfence” paradigm and back to the human. We are all people. Let’s treat each other with respect.

If you genuinely want to know "which tribe specifically, start here with the big picture:

Group totemism was traditionally common among peoples in Africa, India, Oceania (especially in Melanesia), North America, and parts of South America. These peoples include, among others, the Australian Aborigines, the African Pygmies, and various Native American peoples—most notably the Northwest Coast Indians (predominantly fishermen), California Indians, and Northeast Indians. Moreover, group totemism is represented in a distinctive form among the Ugrians and west Siberians (hunters and fishermen who also breed reindeer) as well as among tribes of herdsmen in north and Central Asia.

Individual totemism is widely disseminated. It is found not only among tribes of hunters and harvesters but also among farmers and herdsmen. Individual totemism is especially emphasized among the Australian Aborigines and the American Indians.
