Many Bernie supporters are simply not equipped to view the world in shades of grey. They make these grand proclamations about Bernie and all the things he has not even a one percent chance of ever passing thanks to the make up in Congress, but many actively refuse to even acknowledge that their candidate is, ya know, an asshole on some issues. Just like Hillary, just like every candidate. And so many use that cringe worthy line, "well if Black folk only took the time to get to know Bernie..."
how condescending can you get, ya know?
It's not condescending, but benign ignorance. They're usually people with good hearts, but may not really talk to black people in their everyday lives or yet understand black people aren't a monolith.
It's much better than the hateful kind of ignorance from the other side.
