R.E. — the racist angle.
How so? Because 99.8% of illegals are brown?
Is there a huge illegal alien contingency from the Nordic countries that I missed along the way, ……that ICE is giving a pass to?
Let's start here. I presume that you are not racist, either. But you have been led to beleive that all but .2% of undocumented immigrants are "brown." Let's call that an unconscious bias (we all have them--I picture judges as old white guys even though I often practice in front of women and people of color on the bench). The numbers are difficult to prove conclusively, but estimates are that approximately 7% of undocumented immigrants in 2022 had Europe or Canada as their place of birth. Another 15% come from Asia (including South Asia, so that would probably include "brown" people in many people's minds). Does that still mean that most of these immigrants come from Central and South America? Yes, but the difference between .2 and 7 percent is big (.2. and 22 percent even bigger). Yet, I have never seen an ad attacking all those immigrants from Canada and Europe. Badge would prefer fewer Canadians in Florida--I have heard that.

The Middle East and Africa make up about five percent of undocumented immigrants.
Another reference point. I was a California voter when the state passed prop 187 in the 1990s, which was a voter initiative to deny state benefits to undocumented immigrants (which the federal courts subsequently ruled unconstitutional). At that time, one of the largest groups of undocumented immigrants in California were Canadians. And yet, not a single ad that identified those horrible Canadians as invading our state/country.
Another reference point, I think someone above posted that no one who has been an illegal immigrant should be allowed to become a citizen. So Elon Musk should be deported, right? He has admitted that he was undocumented during college. As CD pointed out above, overstay of visas is a common immigration violation.
It doesn't help your side that the Trump Administration made a big flourish of giving asylum to a handful of white South Africans on a dubious basis, while at the same time revoking protected immigration status for hundreds of thousands of Venezuelan, Cuban, Haitian, and Nicaraguan immigrants.
I have and will continue to agree that we need to do better work on our immigration laws to (a) stem the flow of undocumented immigrants and the abuse of the asylum system, and (b) to provide meaningful paths to citizenship for productive members of our society. That is a conversation that needs to happen. But mass deportations of anyone with undocumented status (targeted entirely at "brown" populations) smacks of something more than that. When our President openly says that he wants more immigrants from Scandinavia, and identifies African, Central, and South American countries as "shit holes," yes, it is fair to infer that there is a racial component to that rhetoric.
One of my favorite responses: "but it's illegal!" So is underage drinking.
