Africans in this country have had a very complicated relationship to Native Americans. Historically allies and kindred spirits who fought against the same system of European Colonization, African Americans have at times also been as guilty of being agents of that same colonization and oppression. A little known historical fact is that Hampton University set out to also educate both Native Americans and African Americans during Reconstruction–by educate, I mean that they primarily sought to assimilate African and Native Americans into White America.
African Americans have also sought to damage First Nation People in other ways by misusing their representations. Witness Pharrell Williams recently donning a Native headdress on a cover of Elle UK.
It seems that black people are willing to commodify sacred symbols when it sells and are ok with calling people Redskins if we are fans (imagine if the teams was called the Washington Darkies!), but want to talk about the importance of maintaining our own culture and heritage.
You need to only do a little more research to realize that Native American Heritage Month is also a celebration of us. Quite literally this month celebrates the Seminole, Cherokee, Muskogee, Creek, and others who are literally comprised of African people, but it also celebrates the spirit of rebellion that speaks to what the experience has been in North America for non-Europeans. Also I cannot conceive of a world where it should be okay to deny and misunderstand any group of people. November is all of our month to say thank you to our foremothers and fathers who have shown us the way.
