Why are Republicans so frightened of Immigration?

FEAR! The Caravan! HATE! Joe Biden!

“We are being conquered,” Stephen Miller said to Fox News’s Jesse Watters. “This is a complete resettlement of America in real time. It took hundreds of years, going back long even before our founding, going back all the way to the earliest days of the colonies in America to slowly build everything that we have.  And now we have millions of people coming in from different cultures and different ways of living and different belief systems. They’re going to take those belief systems with them to America.  So, a generation from now, I am telling you Jesse, people will not know the country that they are living in. These consequences are permanent. Unless there’s massive large-scale deportations by the millions, it will be irrevocable.”

I don't think anyone in modern America has ever so openly declared he wants round-up millions of people.  If you think Republicans are planning a large scale concentration camp system, then you're blissfully unaware of the current ICE detention system and the private prison industrial complex which has been raking in hundreds of millions of dollars a year by incarcerating Americans and people.

The Fear & Anger stimulus that has been drilled into rightwing brain stems by 50 years of ceaseless Republican propaganda is in full swing with the ridiculous Biden Border Crisis.

The biggest question is why are conservatives so scared/angry at immigrants and immigration in general?

Now of course some conservatives are against immigrants because the current wave to the country is comprised of mainly Central and South American people.  But, hating the so-called non-white immigrants is a trend which dates back to the early days of the United States.

Therefore, crime is often cited.  But, while Republicans are absolutely catering to their base of bigots and racists, unless modern Republicans truly believe every one of the 30 million Americans who claims Irish descent is, in fact, a "Fidlam Ben" or everyone of Italian descent worked as an extra on The Sopranos, then the right wing claim that future generations of current Hispanic migrants are going to be dangerous MS13 Rapists who vote Democrat is a ludicrous farce.

The standard response usually is the Democrap Party is inviting migrants here and offering them special free stuff in order to garner future votes.  Besides which the white people proclaim in a huff, my ancestors did it the right way!  And of course we've heard the Great Replacement Theory, which as far as I can tell is the fear by white rightwingers living today that some future generation of "white people" will be treated the way Republicans mistreat out groups today.  In fact, that is precisely the "argument" Stephen Miller laid out on December 20th.

The over-arching answer has to be a combination of blatant racism and Republicans have convinced white people that immigrants are taking away things which should be going to them as citizens.  And would be but, the immigrants got it!  Too Bad!!!  It's a key paradigm of the (Vulture/Late Stage/Crony/Insert modifier here) Capitalist economy of the United States.  There is only one static economic pie and it can only be sub-divided into so many sections.  Thus, any one else slice of the pie can only get bigger when another get's smaller. 

Now, we all know that what Republicans say and what Republicans do are two parallel train tracks which despite non-Euclidean geometry never shall intersect.  Do conservatives actually believe that Republicans would institute a Better than Barack's Obamacare replacement for them if we deport millions of immigrants?  Do conservatives actually believe the "illegals" are getting better treatment and care than them today?  Do conservatives actually believe Republicans would address and help homeless Veterans but for "illegals"?  Do conservatives really believe Republicans would address the opioid epidemic obliterating whites across the Nation but for "illegals"?  Do conservatives actually believe Republicans would safe-guard manufacturing jobs here but for "illegals"?  Do conservatives really believe Republicans will re-create the "White Man's World" of Post WW2 economic hegemony but for the "illegals"?  Do conservatives really believe any of the bullshit Republicans sell them?

Unfortunately, besides the bad faith Republican Party doing everything they can to make American life worse in every way, a large part of this is the timidity of the Democratic Party to tell Republicans to Get Bent with their racist policies while the Corporate Media is paid very well to pretend that Republicans and Democrats generally agree on the framework of the United States and sincerely want to make the Country a place of opportunity, hope, and the American Dream instead of facing the frightening realization that Republicans hate America, seek to oppress, imprison, eliminate many people with the overarching and oft stated goal of replacing the USA with a Theocratic Dictatorship.
