I could be wrong, but I don't think any of those groups want to fundamentally change the country. Most of them seem to point at the constitution and say "we want this". That's a valid position. It may or may not be a good position, but it's valid. Pointing at another nation and saying "I want the US to be that" isn't valid. That's not what the US is, though it's what it might evolve into. The fundamental flaw seems to stem from ignoring that the US is a constitutional republic. Any state could enact most of the changes you want, and some are moving in that direction, that gives you the choices you want. But the idea that every state has to conform to your ideas is ludicrous.
