Because they're not being deported for their Hispanicity. It's for their nationality, which happens to be highly correlated with ethnicity. Why else would US citizen Hispanics have voted in record numbers for the current President?
The admin is overplaying their hand with some shoddy tactics, and the more citizens they drag into the net, the more quickly they'll lose the popular opinion here.

Perhaps because they mistakenly thought he wouldn't do exactly what he said he would do, or that there would be checks & balances to make sure it wasn't too heavy-handed so they personally were not in danger. Now he is doing what he said he would do in that regard (even when accidentally saying the quiet bits out loud) many are somewhat surprised and concerned.
Oddly while not beleiving he would go all-in on the purge many did believe he would do what he said with respect to what they saw as good things (lowering prices, and taxes (for them), ending the Ukraine conflict, keeping America out of other conflicts particularly in the middle-east, releasing any and all Epstein information, …), and are aghast at those things not being carried through as promised on the campaign trail.
Why do you doubt that given the very obvious ethnic persecution going on in the US right now against immigrants, especially Hispanics?
Like, okay, "Ian Butler" in particular doesn't sound terribly Hispanic, but I think that's splitting hairs on the larger point
