It’s interesting that El Salvador is being completely erased from the shithole controversy. Its population is inconveniently not black and tends to consider itself white. Plus, there’s an even more inconvenient issue of MS-13. So now its “Haiti and some African nations.”
It’s very similar to how the discussion of the Brexiters’ anti-immigrant sentiments completely obviates the tensions over the presence in the UK of a large Polish immigrant community. Poles are even whiter than Salvadorans. It’s hard to get any whiter than Poles. So they are erased from the narrative because they simply don’t fit the convenient slogans.
