"But today where I am seeing the most politically motivated historical revisionist pressure is from the far right." - There is no way to evaluate this claim on an objective or quantifiable basis. It is a purely partisan claim based upon your feelings of outrage at the other side's actions. How do you think classically liberal Americans (not you) feel about leftists tearing down statutes and renaming schools? The right isn’t doing that. The left has The 1619 Project, a revisionist agenda spreading lies that those Africans in 1619 were brought as slaves; they weren’t, they came in as indentured servants. How do you think classically liberal Americans feel about how the entire education system is dominated by leftist authoritarian race-mongers who've already gone full historical revisionism in order to inflame racial tensions and use government's systems of mass coercion to force their ideas on everyone including minority dissenters?
