We should but being anti illegal immigration is being anti immigration to an extent because you're anti asylum seeker or even anti refugee (to an extent).
25,465 refugees went to America, yet more than a million immigrants arrived in the US between July 1, 2021 and July 1, 2022.
That's over 2.5% of the immigrants being refugees.
Whereas 55,606 refugees went to Australia, and 145,800 immigrants arrived in Australia within 2021.
That's well over 30% of immigrants in Australia arriving within 2021 being asylum seekers.
Maybe America has a lot of "illegals" because of their regulations, but Australia has always been more relaxed on immigration. However in Australia, immigration has been dropping and hasn't been as high as what the immigration rates were in the Vietnam War times, and it will never be as high as what it used to be because...
1. Australia is already very populated and has caught up with the world, compared to 70 years ago when the White Australia Policy was still around.
2. The xenophobic policies the coalition have had over their 9 years of being in charge, especially Tony Abbott (and you wonder why he was no longer PM less than 2 years after winning his election against Kevin Rudd).
