Its even more cynical in this instance. A fascist state like the US co-opting Tubman is even better optics than just neutering a revolutionary icon. Because of her work against the Confederacy (a great evil that our noble nation saw fit to destroy, something other nations just don't do because they aren't so moral) and all the myths and legends surrounding her, Tubman's profile is effectively tabula rasa for propaganda purposes. Any number of entities can draw on the canvass that is Harriet Tubman. From putting her face on the currency that dominates the world order, leaving in its wake nothing but death and destruction, to making statues for her at the HQ of an intelligence agency that has played a significant role in that aforementioned death and destruction. It further mythologizes the US as a nation that continues to progress morally in a grand Whiggish narrative
