Reading over this post of yours, I see a lot of claims of what Republicans / Conservatives say, which I have to say, I'm not hearing or reading about. What it sounds like is a bunch of talking points issued from some far leftist source without any substance with a smattering of some minimal conclusions.
For instance, no one I've heard is talking about 100% secure border, but a border that isn't a sieve. There are even Republicans / Conservatives talking about :shock: a pathway to becoming legal for the presently long term illegal aliens who are without criminal proceedings against them pending. As often as the Dems have pulled the Lucy trick, and pulled the football out from under Charlie Brown, how often the Dems didn't follow through with their side of the deal, it's little wonder that Republicans / Conservatives aren't willing to be fooled yet again.
Of all the shouts of 'racism', 'racist' and bigot, they are far more often hurled from the left at the right more often than not without substance, and not the other way around.
You keep throwing around the term white nationalists as if it were some sort of code or substitute for the KKK or white supremacists and apply that Republicans / Conservatives, when those two groups are distinctly different with little overlap, painting with an incorrect and overly broad brush.
