This one comes from Daniel Denvir on the Know Your Enemy podcast (as a guest) from June 22 (as a completist, I had to start from the top -- an absolutely awesome podcast, btw, that is well worth starting from the top) (also, the KYE folks were the guests on Denvir's show, to be more precise). What he says can be paraphrased as:
From "Support the troops" to "Back the blue", the right's focus on "the great enemy" has shifted from foreign powers to domestic political opposition. Immigrants are the transition point here as half foreign half domestic elements. [And my note here is that this shift in rhetoric has certainly been playing out in Trump II, with minorities in power as the second station in the transition, perhaps (see Trump's insistence on removing any brown person from any position of power, and invading and occupying cities with brown mayors).
It was one of those "oh!" moments for me when I heard that comment.
