That seems an odd clarification. Do you not believe a democratically elected leader represents a country? Every country has people who disagree with their leaders views, however this clarification on every statement would get tiring quickly.
Whereas when Trump was making overtures to annex Canada, it was useful to the rest of the world to explain that that's something the president was talking about that weekend, as opposed to signs that this might be something the US would actually do.
It's a subtle distinction, of course, and I don't blame anyone outside the US who decides they're not going to bother making it.
I've also heard some similar remarks towards Obama and Biden from the right, but not nearly as much as the left with Trump. The US political sphere is increasingly divided and the Overton window is fractured as well.
Like, are they going to start shooting people? Probably not, probably it will go the same way as the LA invasion where the troops just kinda slink away after Trump gets distracted and Stephen Miller kidnaps all the immigrants he was looking for. But what happens if the Chicago PD tries to obstruct some operation or another on a day Trump got up on the wrong side of the bed?
(That's not a good thing! It's an abuse of the Guard!)
When they do something crazy, I'll be right there with you. But the President has the power to deploy the Guard to protect federal property, and while these deployments are abusive, they're not unlawful. Most of what people say about the Guard actually taking over policing is implausible. So I'm just going to call it out for the bad policy that it is and then not act like the collapse of society is imminent.
The fact that "a large part of the country" doesn't think this is a big deal should tell you something valuable about what the best next moves are.
The real worry is voting. The things you want to watch out for are stationing any military or LEOs at polling places and proscribing mail in voting.
I didn't specifically want to get into the reasoning as to why, beyond the simple fact that there is a large and increasing political divide. Trump is largely representing the majority in terms of what the population wants. The process isn't always what an individual or side may want specifically, but the results have been in line with the stated goals.
I don't have to like the guy to point this out. I usually vote LP myself. I reject far left and far right positions, but find that the far left is a much bigger group. And by "Far" I mean those whose positions are outside what most Americans would consider normative. Far right being around 5%, and doesn't include the majority of "MAGA". Far left being around 15% of the population, including those with cult-like adherence to leftist ideology and disruptive Marxist/Maoist tactics.
