I forgot that you’re the guy who posts stuff from The Bible to make a point…
Those Barbarians that you speak of were organized societies with armies and kings. Romans (and so many others) referred to almost any peoples they hadn’t conquered or come to know well as “barbarians”. The rest is all just completely ahistorical. Yeah the colonies were “Galt’s Gulch”… That’s why they felt necessary to rebel against their king/government and start their own government…
The Bible (interesting as it is) is NOT history etc. etc…
