You'd think it was when he approved the extrajudicial killing of a US citizen with a drone. Imagine someone like Trump running with the precedent he set.

Do you know what those tea taxes were about? The colonists kept starting wars with local tribes and the king got sick of paying for it, so he imposed taxes on the colonies to pay for their own genocidal wars.
The US was founded to guarantee the right to carry out genocide without paying for it all, with a constitution that explicitly kept slavery legal and only allows rich white men to vote. A slave holder who's dentures were made out of human teeth from slaves murdered a bunch of his own soldiers who he'd promised to pay and feed them didn't.
Yeah, there's the nation's soul right there. It's been on the same trajectory since the beginning.
