George washington, franklin, jefferson, madison, all the founders were slave-owning colonizers who explicitly modelled their country after ancient Rome.

It's not a human problem, these were specifically evil people who did not share the same values as the people they murdered and enslaved.

Most countries were not founded in this way.

Yeah, and many of those founders were rich businessmen who didn’t want to pay taxes to the king of England.

They were pissy that the king made it illegal to expand westward and exterminate all of the indigenous people. They were all "no, actually, the British Empire isn't evil enough. Let's make an even bigger and eviller empire than the [at the time] most evil empire on Earth."

This is a human problem, not a national one.

It is a national and class problem, not a human one. Human nature is a bs concept invented to sell the status quo.
