What Texas media and social pressure told them to. That's why we shouldn't let billionaires and liars run the media

They expected deportations of only the "bad mexicans", not understanding thst every mexican is bad to this admin.

The destruction of the left:

“We’re pissed off at the current administration. Everybody’s pissed off down here in south Texas,” the construction executive said, noting that most Hispanics in the area are Catholic. “Remember, we’re conservative, we’re not far left. We’re in the middle, conservative Latinos in south Texas. It doesn’t make sense.”

They expected a scenario that would work out well for themselves. They didn't put any effort into thinking about whether or not any given scenario would work out well for themselves, but the Republican media assured them it would work out, so why would they doubt that?

The Democrats to do the same. This was the year Democrats came up with yet another brilliant strategy to win over "moderate" Republicans by pivoting hard right on immigration, abandoning any talk of "building the wall is racist" in favor of "Trump doesn't actually want to build the wall, we're the ones who will actually do it." Naturally, it didn't do shit to win over anti-immigrant people who still saw them as weak on immigration compared to the Republicans, but it was quite effective at alienating immigrants and pro-immigration people.

Turns out, there's a decent number of Hispanics with conservative inclinations who are willing to overlook them and vote Democrat, so long as they believe the Republicans are racist against them. Since the Democrats decided that criticizing anti-immigrant policies as racist was too alienating to racists, those conservative Hispanics lost the one reason they were willing to vote Democrat and voted based on culture war bullshit instead.

Thinking isn't how Trump supporters become Trump supporters. Fear is.

Their propaganda networks told them to be more concerned about trans people and Haitian immigrants than real important topics.

They didn't consider he'd actually do what he said he would do on immigration because they were too busy cowering in fear over bullshit culture war garbage and hyper focusing on that.

Plus, he'd only go after the bad ones, right?

Probably not concentration camps

he even did it before!

strange, they can't seem to find that person anymore to conduct a follow-up with.

History is filled with people who were promised that we would pretend they were white if they just sold out everyone they cared about. Hasn't actually paid off yet.

Deport the "bad ones." Not realizing that bad is having a skin colour away from mayo.

...in my experience, first-generation-citizen demographics tend to skew hardest against undocumented immigrants; not sure whether that's because they put in the time, effort, + cost to secure their own citizenship and thus resent those who haven't done so in kind, or because they emmigrated to expressly to get away from their native demographic who comprise undocumented immigrants...

Legally documented immigrants are often considerably more strict and harsh in their views on undocumented immigrants. A very "I did it right and so should you have too" mentality. This is particularly strong among refugee immigrants (Cuban and Venezuela, for example). The problem here is the perception that undocumented immigrants are all members of roving street gangs selling drugs and murdering an raping. Farm hands and construction workers can get documentation that passes the checks required of employers. So they weren't expecting their own employees to be swept up in it.

They're not stupid, just heavily propagandized to where they need to experience personal consequence to reconsider. It a perfect chance to have the conversation with them to win them over.

Indeed and racism played a heavy role while voting.
