Yep, it's too hard for him. He's likely embarrassed by what his answer would be.... so he's playing it safe. Don't worry Banjo little buddy, I understand.

Saltpetre "We can be insular"

Oh no we can't.
That would be "discrimination" and you'll be hauled off to court, defamed, blacklisted, picketed, fired, ostracised.

And don't dare voice your opposition.
That would be "vilification" and ditto.

NSW had a state premier recently lamenting that some parts of Sydney were still "monocultural" (i.e. White Australian).

Any attempt by Australians to isolate themselves will be resisted by the authorities, who will use every means to shut us up and shut us down.
Only the immigrants/minorities have the power to choose in these matters.

"Many of our 'white' nationals are far from perfect."

And neither are some anti-racists, who resort to the same crimes, but think the "blood on their hands" is more morally justified.

Banjo has requested you elaborate on your preferred immigration restrictions.
I too would like to know.
