I am Australian, and we have had waves of immigrants for about two centuries. There has been fear of immigration from time to time, notably the Yellow Peril (Chinese) of the nineteenth and early twentieth centuries. I witnessed huge south European immigration in the fifties and sixties, but the intransigence of some – but not all – Muslim immigrants is new.
Until recently an old lady lived in the back unit of our row. She was 101, from Italy, been here since 1955. Didn't speak any english, and not even mainstream Italian, just a dialect. Her 70yo son and his also Italian-origin wife visited and helped her, he spoke Italian and the dialect.
His two sons married non-Italian origin people, spoke little Italian, barely ever visited their grandmother, and
their children know nothing of Italy and its language and culture but their surnames, and their closest involvement with their great-grandmother was picking over her stuff when she left her place to go to a nursing home.
That's how it always is. The migrants who come desperately cling to their culture and do their level best to ensure their kids get it and don't "marry out", but still a good number of them do. Their grandkids mostly ignore the "home" culture and all marry out, and the great-grandkids barely even hear about its existence except on documentaries they're made to watch in school.
Unless, of course, you segregate them in ghettoes and tell them they're evil and inferior, in which case they cling tightly to their culture for centuries and become practically inbred.
I'm old enough to remember all the same bullshit being said about the Vietnamese and Cambodians, then the Lebanese, then the Balkan salad, and so on and so forth. "They won't assimilate... they'll bring trouble here!"
"Yes, organised crime among these new migrants is a terrible thing, if only they could be completely devoid of organised crime like the Italian migrants were."
Now it's Africans and anyone Moslem.
And it's all bullshit, and always was. And the proposed laws are undemocratic and should not be signed into law.
