What do you think ethnicity is? There were times when Georgian consisted of Eastern and Western Kingdoms and it is historically inaccurate to state that Colchs were ethnically the same as people from the East. Yet centuries passed, people mixed and hence the Georgian ethnicity. An American qualify as an ethnicity. You make it sound as if all modern ethnic groups were out there in the present form form the beginning.They were not, we are all mix of something.
