By any definition Rome was a great empire. The United States enslaved a lot of people. I still consider it a great nation. The Barbarians did not “collapse” Rome. It decayed from within and the Germanic tribes took advantage of the collapse. At the time of the collapse Christianity was the official religion.
Not only is your statement blatantly false but typical of a drive-by socialist troll who hates America and ignores reality. Now go back to DU you commie rat!
