Actually, what Rev. Barber is talking about a very real issue of immigration-racism regarding the disparate treatment between the large number of undocumented or dubiously documented light-complected Russian and other Slavic immigrants, and the Latinx's - NOT that "The Russians are coming" crap of the Hillary campaign.
Pittsburgh has seen a big influx of Russians and east Europeans who are either undocumented or have some peculiarly expedited means of getting green cards. Our Jewish neighborhood of Squirrel Hill is turning into a "little Moscow" in the same manner that formerly Jewish Brighton Beach in New York is now called "Little Odessa". The Russians work non-union low wage construction jobs and drive long haul trucks. Monitor CB radio chat along an Interstate highway these days and on some channels you will hear Russian, not southern-US English.
But meanwhile, our tiny Latino community in Beechview and Brookline is being broken up, arrested and deported. The ones here legally have seen their shops vandalized with racist graffiti.
Why the disparate treatment? The usual culprit - one of them has too much melanin, the other the whitest of the white people.
