You do realize that this country was founded through a bloody revolution, right? The Founders were political revolutionaries, and took up arms. Did you think they just voted the British out and the British just left in embarrassment?I assume there are specific mechanisms in place to alter or abolish a government, because otherwise any group of people deeming the government to be against their rights would just try to undermine it through vigilantism or illegal means (e.g., the January 6 insurrectionists).
The US legal system has been increasingly looking tenuous and flawed in the last several years, though, and this is something many analysts both from the US and elsewhere have commented on. I have to wonder how well the Founding Fathers' vision of protecting rights would even work out in practice should it need to be implemented today.
Now there is a part in the Declaration that warns against doing this on a whim:
"Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed."
However:
"But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security."
Yes, we have an inherent right to overthrow abusive governments when other recourses have failed. That's the right of all humans.
