The U.S. flag should fly the colors of the true founders of the country. Red for the natives that were destroyed, deceived, and erased from the history books. Black for the people that were forced to sacrifice their civilizations, families, and future to build a nation that hates them. And white for the people that profited from the cruelty and systemic racism that built a "democracy."
With apologies top the many contributing colors that are not represented by the big three (the many beautiful shades of brown and yellow, in case you were wondering).
