Well,

The US is both a republic (a form of state in which the country is considered a "common good" and not the legal propriety of the sovereign) and a democracy (a system of governing in which all citizens have an equal say in the choices of government). (emphasis added)
That bolded part just isn't true - consider DC citizens, who have no Senatorial
or House of Representatives representation at all. (No, nonvoting delegates don't count.)
The US is a republic of democratic states and territories. Not a democracy by
iguana_tonante's own definition. I don't see why this simple observation merits condescension.
I see your point, and I think it's a good observation. But all it shows is that the US is not a
perfect representative democracy, not that it isn't a democracy at all. In fact, it can be argued (right or wrong, that's beside the point) that a upper house less beheld to fleeting popular sentiment (as the British House of Lords) or representing constituent entities of the countries instead of citizens (as the US Senate) might be a favourable feature of a democracy, to improve political stability or long-term planning.
It's one of my fundamental convictions, that peoples that want to be independent and form their own nation should be allowed to do so. That goes for the Scottish, and the Basques, the Palestinians the South Sudanese, the East Timoreans, and the Quebecois, the Tibetans, the Chechens and for all I care also the Louisianians and Texans, I support them all.
I'm not sure I agree (or at least, not completely). Self-determination is sovereign, but there is also an issue of size. Say, for example, Louisiana secedes from the US: what would happen if New Orleans wants to secede from the newly independent Louisiana (as an exclave of the US or its own city-state)? Should it be able to? The Greater New Orleans Area has more than 1 million people, about 1/4 of all inhabitants of Louisiana, so hardly a small community in comparison. I dislike making slippery-slope arguments, but this is something you have to consider.
