"Indians" itself is a term that can be problematic, as it's a broad generalization that doesn't reflect the diverse cultures and histories of Indigenous people across North America. It's best to use specific tribal names or "Indigenous people" when referring to them.
If you're interested in learning more about specific tribes or Indigenous cultures, I recommend checking out resources from reputable organizations like:
* Native American Rights Fund: [https://www.narf.org/](https://www.narf.org/)
* National Congress of American Indians: [https://www.ncai.org/](https://www.ncai.org/)
* American Indian and Alaska Native Culture & Arts Development: [https://www.aiaadc.org/](https://www.aiaadc.org/)
Remember, it's important to be respectful and accurate when discussing Indigenous peoples.
