Then I learned some things that made me question that view.
The problem I had, is I learned that the take over was really much more of a hand over. Romans had become lazy. They had no values or sense of self reliance or control. They had no loyalty or many virtues to talk about at all. In consequence, eventually it was the barbarians that made up the most of the military. The take over had more to do with the weaknesses of a corrupt lazy Empire than anything else.
Even some early Christians remarked that the Barbarians seemed to have more Christian virtues than the Romans did... That might explain the spectacular success early Christianity had at converting boat loads at them... But that's another story.
Who are the new uncivilized Barbarians? Apparently Conservatives:
"Canada is too civilized and precious to be messed up [by Conservatives]." - Robin Williams
Liberals and Left wingers have even today taken to calling themselves "progressive." In other words Conservatives are then backwards, regressive, uncivilized folk.
Just a warning to those civilized priviledged few: The Barbarians eventually inherited Europe.
