You know, in the 1930's there is little question that if Trumpian technique were employed, the US would have banned all non-white residents of Hawaii from traveling to the US.  Back then Hawaii was being loudly billed across the US in the media as a land of righteous, yet endangered whites, living amongst rapist savages (non-whites, although the evidence seems to indicate just the opposite).  The viewpoint was deep and broad.  For America, it was simply a matter of fact.  All non-whites from Hawaii were dangerous.  Worst than terrorists even.  All America concluded that  (white) women were in grave jeopardy at the hands of non-white Hawaii residents.
