This country was hardly founded on Washington’s ethics or spirituality. While he definitely served an important role as general and president, to my knowledge he had no personal involvement with drafting the content of the Declaration of Independence, the Constitution or the Bill of Rights. He was certainly entitled to his own views, religious or not, but they are his, not his country’s.
Washington also held strongly that our nation should stay out of world affairs (which didn’t last to long in our national policy). And he expressed abolitionist sympathies, though while in the White House he rotated the White House slaves in and out of the state to avoid a state law that would free slaves in residence six months or more. In all fairness he was the only founding father to free his slaves, but not until after he and his wife no longer needed them, ie after they both died.
So yes, agree with George whenever you do, but know that his opinions were no more sacred or fundamentally true than they were synonymous with the values of this country.
