To your question:
Keep up what you're doing, the history of Turtle Island (the Americas) has only become public knowledge in the last 50 years - or less e.g. the fact that Indigenous people lived in these lands was not accurately described in school textbooks 30 years ago, maybe even 10 years ago.
Will the Smithsonian admit to that? Well known archeologists, William Henry Holmes and Alex Hrdlicka denied that Indigenous people existed before 3000 years ago, even after 32 bison bones and a folsom point were sent to the Smithsonian.

There is A LOT of work to be done in shifting misconceptions and bad information, that have been hammered into people's heads for the last 200 years.
