Byzantines didn't "become more Greek than Roman". They were already Greek to start with.
But anyways... lets not have me rant about that part.
The population was Greek. The empire was split into West and East. West centered on Rome (before the fall) and the East on Constantinople (A town in Greek). From the division working language was Greek.
Greek language and couture was more prevalent in the Eastern Roman Empire. When the fall of the West Byzantine court held onto the Latin language for official decrees and other state documents, but eventually even that was lost to the grater Greek influence.

Totalitarian government is when a single group completely takes over and makes the people subservient to the state (they make all of the rules) and if there was more than one group, opinions may differ and actions may be more diverse, and it wouldn't have total control over the decisions anymore. Ex: Hitler- changed laws to what he saw fit, changed culture, controlled how people were treated, threw Jew's in concentration camps because of a personal bias, etc. He had total control, thus totalitarian gov.
