Multicultural versus monocultural societies and countries

[Montmorency]

Yet another problem:

On what basis do you distinguish "group cultures"? How are you going to categorize each and every human such that they can be placed with their groups and, you know, not bring along any other cultures? People are multicultural to a far greater extent than implied by even the smallest-scale terminological specifications.

I don't want to disparage you, but if you can't explain some more of the concrete details of this worldview in a way that addresses these issues, it will be revealed as another poorly-thought-out utopian thought-exercise fatally riddled with inconsistencies
