Serious question though, how do we secede? Countries separate/split. To just say we can't seems to defy the obvious history around the world that it happens. So the question is how. We can do it, what's the process to make it happen? I'm tired of supporting/accommodating fucking Nazi states.
That question was settled back in 1865: there is no mechanism for that act.
Saying "you can't secede" ignores reality where localities can, and do, declare independence. It can happen regardless of what "official" mechanism exists. So what I'm hearing is, California just flat out says they're seceding and dares the US to stop it.
Okay, granted. However there’s the practicals to consider, like interstate commerce, military bases, out of state workers and vacationers, energy and water infrastructure, etc..
Given the alternative is being a controlled and occupied territory of the 4th Reich, I'll take the secession option and it's complications.
