Problem -“Tyrannical” is not precise language.
We are a constitutional republic. Specifically. The second amendment is intended to allow Americans to resist if the government fails to follow the constitution and to resist those (foreign or domestic) who would replace constitutional government with “something else.”
Upholding and defending the constitution is a two way street. The government has to follow constitutional process but so do the people. That means attempting to redress grievances via elections, legislatures and the courts.
If you dig into the actual boogaloo extremists they espouse the idea that elections, legislation and courts are old, slow bullshit for boomers and that it is simply “time to get it on.”
This is not unique to the Boogaloo extremists, it is just another form of accelerationism.
What they either don’t get or intentionally ignore is following the constitution is as much about the process as the outcome. It’s not a guarantee you will get what you want.
