Well, I’ve since determined the poster basically objects to Dignitatis humanae, or at least chooses to ignore it, so at that point what’s there to say? He doesn’t believe in religious freedom as a basic right, wants a theocracy of some degree or another, but believes it will work out just fine because apparently a Catholic government would be immune to all the evils that have befallen other governments that have melded themselves with religion, because they are either Protestant or Islamic heretics.
I’ll be charitable and suggest the poster is rather naive. Ironically, the most successful Christian governments were the Christian-era Roman regime and the Carolingian Empire, but in the former case, the Emperor basically sat astride the Church, and while individual bishops might bristle under the overarching governance of their Imperial benefactors, it did prove quite successful at ousting heretics, creating Orthodoxy and merging state institutions and the Church (or rather, the Church was effectively a state institution).
The Carolingian Empire was a bit of a delicate balancing act, but basically Charlemagne and Rome found equal ground; Charlemagne had enormous influence over the appointing of Bishops within his Empire, but in effect worked in a sort of a political alliance with the Papacy. It was an elegant system, what I’d probably call the high point of Christian civilization as a largely united governing institution, but it didn’t long survive Charlemagne, and when later Emperors tried to strike the same bargain with Rome, they found the Papacy less willing to share power, and Rome made it clear it was at the top of the heap. This lead to all sorts of strife, and I’d say the Papacy’s increasing intransigence is at least partially responsible for the ill will among many German princes that lead to the eager adoption of Martin Luther’s ideas.
