Your page does not say who you are or what your historical credentials might be. Historian was my profession with the best possible credentials, SoCalPubbie. I challenged your interpretation. That would not normally be answered by text from the encyclopedia.
A fundamental parallel remains. Just as the Romans had colonized Gaul for 400 years, so also did Europeans colonize Africa, the Middle East and South America. In spite of much contact over centuries, however, huge gaps in development remained. Then migrations overwhelmed the developed world and destroyed civilization. Can it and will it happen again?
No I am not a historian. I am not I am a liberal either, and since you accused me of being one I question not your background but your judgement.
The fact remains that the Goths were poorly treated by the Romans, or do you disagree with that?
