Okay, I get it.
You have a bug up your nose about anything that can possibly be considered Greek.
I would like to point out that I was not referencing the relative humanity or decency of government in North Africa over the centuries, merely its wealth, power and effectiveness.
By the time Justinian I reconquered most of the North African littoral, that had declined quite a bit from its heyday under the Romans. The Exarchate of Carthage was reasonably stable, but was unable to put up any great resistance to Muslim conquest, which was resisted primarily by native Berbers. I would like to point out that the Romans of Caesar or even Constantine would have squashed the Muslims like a bug. That differential is what I am talking about when I refer to a civilizational decline.
As in Syria and Eqypt, and later in Spain, unified resistance in North Africa to Muslim aggression was greatly hampered by the long-standing Byzantine policy of religious persecution of “heretics.” Many of the heretics, not unreasonably, felt they would be better off under Muslim than Byzantine rule. Which they probably were, initially. In the long run it didn’t work out so well.
Your original statement is patently false so ther is no need to go into a lengthy historical summary to deflect from your original BS:
“North Africa was definitely going backwards from the Roman peak, civilization-wise”
Precisely, “civilization -wise” - North African was in far better moral shape than during the pagan Roman period.
