Not against those same founding fathers, who where not truly religious. George III was very anti-Catholic, never-the-less, even tho I myself am a Catholic, had I lived at the time I would probably have sided with the Loyalists.
You seem to be comparing obeying God under unjust conditions with obeying God under friendly and biblically conducive conditions.
So you maintain that democracy and republicanism will encourage biblically conducive conditions? I don't see it, not here and now, nor in the history of said government. God said he made Kings and Emperors to do his will... nowhere did he claim authorship of republics. If democracy is a valid form of government should the peoples' voice have superseded that of Moses when they sought to worship a golden calf? Beware of relying on a majority to justify yourself, for many will try to enter through the wide gate that leadeth to destruction.
Democracy is based on the pagan principle that might makes right. Since ultimate power always resided amung the masses, for they can as a group always refuse to obey, or worse, it is assumed that they are also right. Thus legitimacy is based on man not God. And the words of St Paul are forgotten, "For princes are not a terror to the good work, but to the evil."
The founding fathers knew that democracy is dangerious tho they did not really understand why, and to this end they set up multiple "checks and balances." A stopgap for a problem they could not solve, the work of man (and pagan man at that), and thus bound for ultimate destruction.
