Is this the same group who don't want history taught in schools?
That the natives were dehumanised as "savages" in the declaration. That this racist depiction america was founded on would later be seen with two statues of "savages" infront of the US Capitol building (like the White House, another building built by slaves) which stood for over a century before their removal in the 1950s.
That thomas jefferson, pioneer of scientic racism, wrote in 1785: "blacks are inferior to whites in the endowments of body and mind"...and although he opposed to race mixing he did rape at least one of his 600 slaves, and also wrote: "the improvement of the blacks in body and mind, in the first instance of their mixture with the whites, has been observed by every one, and proves that their inferiority is not the effect merely of their condition of life".
That george washington hired a slave catcher during the revolutionary war to try and recapture some of the 18 of his 600 slaves who fled his Mount Vernon plantation inorder to join with the British to gain their freedom (upon doing so these slaves were given jackets with "liberty to slaves" stitched on them). That at the end of the war he demanded their return, but they sailed out if New York harbour to freedom.
That the national 'slave defending' anthem (star spangled banner), written by another slave owning tyrant Francis Scott Key, has a third verse (conveniently no longer sung) which excoriates these slaves (mentioned above) who had the audacity to seek freedom by joining with the British. This is why blacks don't sing this slave anthem (they have their own.."lift every voice and sing"). Nobody should be singing it.
That the fugitive slave clause of the constitution, which came into effect with the fugitive slave act of 1793 (signed by washington), made it a federal crime to prevent slave owners (Jefferson, washington and co.) from recovering their property (slaves). That these slave owners took out adverts in newspapers offering a reward to those who could recapture their slaves.
That only whites are americans per the 1790 naturalization act (precluded non whites from citizenship). This restriction continued into the 1920s when an Indian was denied citizenship as he "wasn't deemed white".

That only (wealthy) whites could vote prior to 1870, and although not a slave owner like washington and jefferson, Abraham Lincoln was against that race based vote changing, stating in 1858: "I am not, nor ever have been in favor of making voters or jurors of negroes, nor of qualifying them to hold office, nor to intermarry with white people"
That the ban of interracial marriage (anti-miscegenation, another american concept which the Nazis would emulate in their Nuremburg laws) only ended in 1967.
That america was 90% white prior to the 1965 immigration act which ended two centuries of immigration restriction on non whites, a policy which Hitler praised in Mein Kampf; "the American Union categorically refuses the immigration of physically unhealthy elements, and simply excludes the immigration of certain races."
And a religious one.....That the pilgrims (puritans) were an extremist persecting cult who banned everything that didn't align with their narrow beliefs. The only thing to be thankful for is that their reign of terror ended so quickly.
This "moms for liberty", an anti-freedom censorship group, want an ignorant populous. They perpetuate hate and bigotry by trying to pretend history never happened, so theres no learning from it, no humility. Their ilk is the reason america remains so toxic today. In contrast, Germany, just 80 years after the holocaust, although not perfect, owns their history, its taught in schools, which is why they have topped polls (twice by the BBC) for their tolerance to diversity today.
