It's worth looking at how that environment is produced too. There's a need for cheap labor in agriculture, laundry, hospitality and textile industries that dovetails well with the US's history of anti-mexican racism (grounded in the need to dehumanizing indigenous people to steal their land as well as the US-Mexico war).

By controlling people's movement through the border regime, we can make them willing to take sub-minimum wage jobs, while also keeping Mexico poor through lopsided trade agreements like NAFTA and low level insurgency achieved by escalating the drug war and flooding the country with weapons.

In this context of US oppression of Mexicans, it becomes necessary to dehumanize them to justify the violence. This is where fox news comes in. Hell, even CNN plays a role by creating categories of migrants some good and some bad, and playing them against each other while justifying border control (think about the rhetoric about dreamers vs drug smugglers).

To change this environment, we either need to undercut this propaganda by organizing white and brown workers together, or either take back control of media from big business or make our own media with similar reach.

Oh it's more complicated than that, but getting in to the psychology of fascism involves a lot of typing and there are more articulate authors who have already explained it at length.

it is that they live in an environment where they are told that Hispanic people are a threat, that caravans are "invading" the US to pillage it

They already hated brown people long before that.

These people don't have to be told a damn thing. They suspect the worst of the best, the best of the worst, and when it comes to 'others' they have nothing but scorn, even if it's completely baseless. It seems to be a kind of narcissism.

"Good people can't be good because I look bad by comparison. Bad people are good because I look good by comparison. Other people don't look like me at all and so we must assume the absolute worst..."

To be fair though, I don't know how we can sustain illegal immigration of low income workers.

I'm reminded of their support for that random Democrat from Hawaii. Turns out she was anti gay and pro intervention.

Yah the people I know haven't even read a single thing about the "don't say gay" bill nor have they even read 1 thing about the Trump documents. They call it a political hit job and I ask them about the specifics of the documents that were IN HIS BATHROOM and they legit hadn't heard any of it lol. It's because the media they consume actively avoid its.

I'd argue that MOST of these whackos are so disconnected from reality because all they listen to is pod casts and watch fox news. They don't read articles written by actual journalists with sources.
