I would be surprised if it was right-wingers burning the flag in Colorado, although there are so many currents of thought within what is called 'the Right', including some which are clinically insane, that I wouldn't be
extremely surprised. (I used to spend a lot of time on a couple of militia sites. Whereas the stereotype rightwinger 'backs the Blue', you would not infrequently come across people who were rightwing cop-haters. Probably because of a bad divorce and being forced to pay alimony. So it's possible to conceive of some of them -- like the 'Boogaloo Bois' -- who genuinely hate America, but with mainly rightwing instead of leftwing prejudices.)
As for the Confederate Flag. There are two types of white Southerner (of which I am one) who don't feel your sort of hostility to the Confederate Flag.
(1) Most of us see the Civil War as a huge national tragedy -- those of us who know a bit about slavery and the world, know that it was brought on by the arrogance and stupidity of the Slavocracy, who could easily have negotiated a very lucrative buy-out, at taxpayers' expense, the way British slaveowners did.
Any thinking person by the middle of the 19th Century knew slavery was on the way out in the civilized world. But the South had such a strong position in Congress that the slave-owners thought they could defy history -- just like the French and Russian ruling classes did. And then a representative of this way of thinking went and assassinated Lincoln, who, rightly, would have been the best friend the defeated South had, being a truly great man.
Although it has probably died down a lot by now since when I lived in the South, there is a kind of sentimental class/regional feeling about the Confederate Flag. I believe there was a popular television show where the main characters, or some of them, had a giant Confederate battle flag painted on the roof of their car. [

Of course now it's totally unPolitically Correct, but at the time, no one thought it meant being a white supremacist -- it was a general symbol of rebellion, against arrogant well-heeled educated Northern Yankees, although of course this attidude to this symbol, given its history, was restricted to whites.
Now, of course, the whole Confederacy thing allows liberals who vote to honor the Soviet spy Ethel Rosenberg to pretend to be patriots. It's ironic, because Southern whites used to volunteer for the military well out of proportion to their numbers. (Now, apparently, no one is volunteering for the military.)
(2) The second kind of Southerner who flies the Confederate battle flag
is a white supremacist. Their main organization is here: [
https://leagueofthesouth.com ] They aren't openly white supremacists but no one should be fooled.
They would have some problems if they did manage to get independence, because today less than 60% of the South is white: a perfect figure for inter-ethnic civil war. [
https://statisticalatlas.com/region/South/Race-and-Ethnicity ] On the other hand, Blacks in the South -- in the sort of chaos that made Southern independence a practical possibility -- might want their own nation as well. This would require massive population transfers, a la Yugoslavia or the Raj (India/Pakistan), which are always bloody.
Some of these people pretend that the Civil War was not about slavery, but about tarrifs, and defend the South on the grounds of national self-determination, abstractly no bad thing. But in reality, if the South had gotten her independence, it would have set a precedent, and we would probably have ended up with four or five separate nations on the current territory of the US. We would have been all set to repeat Europe's national wars among ourselves, and would also have been unable to intervene in the world to stop Nazi-ism and Communism. So it's good that the North won. [Winston Churchill once wrote an essay on this subject, as an 'alernative history' in which the South gets its independence, and as a result, we don't have WWI. It's summarized here: [
Churchill’s Alternative History: Robert E. Lee’s Triumph at Gettysburg ]
And I suppose the people who show up with Confederate flags and other Confederate regalia at conservative demonstrations, embarrassing us, may include some wily false flag leftists -- doing the same to us as the open Communists who turn up at progressive demos with hammer-and-sickle flags do to liberals. But probably the great majority of both of them are working for free.
The thing that should interest political people is the question of the multi-national character of the US. Many people who are new Americans, or the descendants thereof, retain a dual national identity: they're Irish-Americans or Italian-Americans or Jewish-Americans (since the establishment of Israel gave them a state) or Mexican-Americans.
Some Southerners have same sort of dual identity: Americans, but also Southerners. (I leave out African-Americans from this list, as there are very few of them who actually identify with Africa, and for good reason. And for the same reason, when some Mexican-Americans became 'nationalists' in the 1970s, they had to invent a nation, 'Aztlan', because they were ashamed of Mexico.) This dual-identity tends to fade with each new generation.
As for 'most people' not 'having a clue about anything' and basing our beliefs about 'what is' -- you are right, if we're talking about something like the age of the earth, or the composition of brass. These are just objective facts. (Really, you would only be right if you said 'many', not 'most': American knowledge about science is actually greater than you might think. Details are here: [
What Americans Know About Science ] This survey contrasts Republicans' knowledge about science with Democrats' knowledge, 'extreme' partisans' knowledge (for both sides) with moderates' knowledge, whites' knowledge with other races. It's very interesting, although if you're on the Left and looking for your preconceptions about how stupid the Right is to be vindicated, you shouldn't look at it.)
But if we're talking about human consciousness, then it's exactly what we must do, i.e. to try to determine what someone really thinks/feels about, say, the American flag. It's not the sort of thing we're likely to be able to find objective evidence for, but I would assert that people who burn the flag are not protesting the particular current government in power, nor are they protesting particular clauses of the Constitution. Their hatred is for the whole American system -- which most of them couldn't analyze in any depth, their anarchism not being ideological, but personal.
And, to be fair, they're not all that different in this respect from many people on the Right, who don't have a thoroughly worked-out ideology. Their love of country (and therefore for its flag) is not based on some dispassionate analysis of America and its role in advancing human welfare, or otherwise ... it's not instrumental. They feel it's their country, period. Even if many of them have not, over the last few decades, had a very satisfactory time of it, as globalization destroys their livelihoods.
I should say that I am all for Leftists burning the flag at demonstrations. It's a powerful statement of their true goal.
