Which in many ways is the issue at hand -- the hypocrisy of arguing about "erasing history" when that's what's been done from the start.
Not just with regards to Washington and the other "founding fathers" but with regards to the histories of those they killed and enslaved as well -- people are so quick to talk about the lack of education in the black community or the lack of "family values" but even quicker to ignore the fact that unlike many other immigrants who came by choice, African families and traditions were both demeaned and destroyed upon arrival while said Africans were beaten and killed for trying to educate themselves and still are forced to endure de facto segregation into blatantly separate and unequal school districts while being under constant threat of abuse and death by a routinely unchecked "police" force that has it's origins in the slave patrols of said past.
It makes sense many downplay the severity of systemic racism and white supremacy given that they are likewise downplayed in our textbooks.
Likewise there is little mention of the positive accomplishments of non-whites in America -- just a few topics on token civil rights leaders like MLK and Cesar Chavez, some discussion of Chinese immigration and their work on the railroads and a paragraph or so about George Washington Carver, Langston Hughes or the Windtalkers during WW2 -- while the vast majority of said American history involves a growing "minority" population being taught to respect a vast litany of white men many of whom considered people like myself to be less than human.
Even when teaching the history of individuals like MLK, the racist backlash against said movement is downplayed and then subsequently echoed in the modent era -- most people don't know that it wasn't the protests that led to actual change but the "riots" that happened after he was killed.

It could easily be argued that we keep experiencing the same problems with regards to racism and white supremacy as we did four hundred years ago because many American schools refuse to teach the
whole truth about history -- such as the numerous riots over police brutality in the past -- and without these facts students (and future voters) can't make objective judgments about how to best to address said issues moving forward.
If white voters would actually pay heed to said peaceful protests (such as marching on Washington or taking a knee) then there would be no need for repeated uprisings to press the need for actual social progress. Suppress people's votes and oppress their rights and they will naturally rebel -- that's something people claiming to respect Washington should inherently understand but that message gets lost when even he didn't respect the basic human rights of black people and other "minorities".
It's understandable that many Americans hold individuals such as Washington and Jefferson in high reverance but it's equally important that we not be taught an incomplete and overtly biased (i.e. white supremacist) version of this nation's history assuming we want to move forward together as a nation.
It's exactly that kind of mentality that leads to Americans thinking "white" lives and histories are more important than others.
