No humanity cannot live together in the same location under authoritarian multiculturalist principles and maintain their identities.

Not segregation but autonomous areas. Also people should be able to create groups based on their identity even if it is a racial one. This already happens in ethnic clubs and through other processes such as gentrification and slumification. These groups need to follow the laws of the state or nation but they can exert influence to change the laws. A group can opt to cessede from the nation if the nation doesn't meet the needs of the group identity. These ideas are already established in different contexts.

Yuyutsu,

Thank you for your comments and advice.

They are wise words and I know they came from your heart.

Canem Malum,

Thank you for your contribution to this discussion.
There are of course many diverse communities in this
country. And they do practice their own languages and
cultures. This is true in many countries. Yet these
communities also abide by the rule of law and are able to
live peacefully side by side. Many people find comfort in
associating with their own kind - where they are more
welcomed, feel more at ease, and are better understood.
The younger generations possibly find it easier to mingle
and assimilate. Some things take time.

Talking from my own experience - I grew up being
involved with the Lithuanian Community. It was
during a time when assimilation was required. But
because Lithuanians fled from persecution and
from the Soviet Regime - they felt an obligation
to try to preserve their culture, values and traditions.
Hence the communities that were formed.

Many, however did assimilate, inter-married, and have
richly contributed to this country in many ways.

Each community is different. But as far as I know -
each has made huge contributions in making this country
better.

Many Lithuanians have been back to visit now
that Lithuania has re-gained its independence
from the Soviet Regime. And they have visited
multiple times and continue to do so.
However only a tiny minority have returned
to live permanently. Most prefer Australia
and see this country as their own.

I think many other people - such as the Greeks,
Italians, and many others - also feel the same
way. Australia is now their country. Where they
feel they do belong.

There are migrants & there are people looking for an easy existence provided by others !
It only takes insipid bureaudroids for the latter to get their wish granted !

Not all bureaucrats are insipid. Neither do all people
mis-use our systems. We have to allow for individua
differences in each group.
