What The Trump and now Republican agenda actually is has nothing to do with protecting America. It has everything to do with preserving white European ancestry Republican rule. ... Trump and Republicans see immigrants both legal and illegal as Democratic votes and the changing of America's collective skin color from white to shades of brown with whites being bumped. Trump and Republicans are resisting the demographic change of America. … ultimately reasonable people of all skin colors will make their case for America. You can always camouflage actual motivations by wrapping yourself in the flag, thumping a bible, and shouting patriotism.
Ah yes, someone else drunk on slogans of mock-righteousness phraseology - useful only to the intellectually lazy (and ungifted). Perhaps if you were more intellectually and historically grounded you might have discovered that parroting the left catechism is pretend argument, canned ranting.
Peruse the 90 year old history of your ideological forefathers and its an old line; your ancestral new leftists and communists, denounced other Presidents as fascists and oppressors, wailing about "new chains for labor" and Presidential "policies have(ing) but one purpose, to make the workers and farmers and middle classes pay the costs of the crisis, to preserve the profits of the big capitalists at all costs, to establish fascism and to wage imperialist war abroad ."...yada, yada, yada.
However, should you try some independent thinking you might arrive at something uncanned - something that isn't cadre speak.
Yes the Trump and Republican agenda have had more than one purpose, one of them to do with protecting THE WELL BEING of America. In general, Americans who voted for Trump (Democrat and Republican) feel politicians have betrayed them (in particular, the establishment Republican mainstream) and ignored the sense that the blue collar middle class has regressed, rather than advanced, with the loss of manufacturing jobs. No one, except Trump, was serious about the use of tariffs to make an equal playing field nor was anyone serious about low cost immigrant labor taking jobs and living off welfare programs at the tax cost of long-time, native born, Americans.
That doesn't mean their was not also a sense of lost culture and shared values, a belief that those in unprotected classes were being economically harmed by "protected classes", that folks were tired of being called racists on every social issue when they wanted equal treatment, and the political landscape was nothing but a sea of identity politics (with their race or gender being the object of denunciation, direct or implied).
So naturally the left, having largely abandoned concern over the blue collar class (except Sanders), and far more obsessed over race and gender (and those glass ceilings for rich female executives) got working class backlash - much harder than anyone could have anticipated.
Mind you I don't agree that all these concerns were necessarily valid, but I have no need to ignore their actual motivation to fit my political prejudices (as you do).
So yes, illegal immigration has been a hot issue beginning the late 1970s, when even many blue collar Democratic leaders were on the side of the heritage population. And for the last 50 years the ONLY thing that has changed is the transformation of the left into promoters of identity politics (over class) and their growing awareness that but for the relentless infusion of new foreign voters, the demographics would be running against them rather than for them. In other words, both assimilation and a stable population is the enemy to Democratic electoral success - something that Democrats recognized long before mainstream Republican leaders (and some still don't get it).
"The competing agendas" of Republicans has not changed but there has been growing agreement that whatever reform may be adopted, 50 years of six and seven digit illegal immigration is not acceptable.
All of which leads me to ask, so what? What is wrong with preserving the historic culture of Europe or Western Civilization? What is wrong with protecting blue collar jobs? What is wrong for ANY RACE or GROUP to feeling threatened by extinction - be they American Indians, WASPs, or Jews? What is wrong with assimilation? What is wrong with attempting to check the impact of population growth and the loss of farmland, the transformation if rural towns into enclaves for those with money, and skyrocketing housing prices? What is wrong with treating our right to make legal vote as at least as serious as of what is required to open a bank account or cash a check, a photo ID?
