It used to be that references to undocumented immigrants as “invaders” was reserved for the outermost fringes of the body politic.
Stormfront. Short wave. Nazi/Racist/Neo-Confederate bulletin boards. Infowars.
Now, because of an unprecedented humanitarian crisis, the right-wing freakout over “illegal” “invaders” has become commonplace. Neo-Nazi hate-speech is now mainstreamed.
Add to that the sudden appearance of underemployed, angry white folk, (whose immigrant ancestors came from somewhere), who have nothing better to do all day than to turn parts of the American desert into little clones of Afghanistan - complete with weapons and extralegal checkpoints.
Not to put too fine a point on it all, but what’s going on along the US-Mexican border is unprecedented - youngsters are crossing into the US en masse and rather than running from Border Patrol in order to get further into the US, they are surrendering immediately upon arrival, just like the Cubans do under our unusually generous “dry foot” policy.
(Hint: Just tell the wingnuts that these kids are from Cuba, and maybe they’ll treat them as human beings.)
