In short, they are saying freedom is slavery.
It has been said, and it is a common platform expression, that it is well to prefer the man above the dollar, as if the preservation of property rights has some other purpose than the assistance to and the uplifting of human rights. Private property was not established in order to gratify love of some material wealth or capital. It was established as an instrumentality in the progress of civilization and the uplifting of man, and it is equality of opportunity that private property promotes by assuring to man the result of his own labor, thrift, and self-restraint. When, therefore, the demagogue mounts the platform and announces that he prefers the man above the dollar, he ought to be interrogated as to what he means thereby -- whether he is in favor of abolishing the right of the institution of private property and of taking away from the poor man the opportunity to become wealthy by the use of the abilities that God has given him, the cultivation of the virtues with which practice of self-restraint and the exercise of moral courage will fortify him.
Find a copy of Lewis and Clarks Diaries of there expedition. Pat particular attention to their description of what the the indigenous natives of the Columbia River Valley were like. These were hardened men. It’s enough to make your eyes run.
These "Land Acknowledgments" are the latest virtue-signaling, meaningless gesture. If these people REALLY believed this crap, they'd sign the deeds to their homes and land over to the Indians. Otherwise it's just another feel-good empty steaming pile of hypocrisy, just like the celebrities who do not sell their private jets, yachts, and mansions to reduce their "carbon footprints."
They put up a stupid slide, spend five seconds reading it, then feel very smug and self-satisfied about how much they CARE for the Native Americans.
