I'm not expecting people to stan Bernie or anything, but a some of this ill will comes from 3rd party assholes remarking about what they expected "the blacks" to do.
Bernie is from Vermont where they are more frontier style libertarian than progressive liberal, but I'm not going to imagine that Hillary has any more intent for issues that affect black and brown people than Bernie. It may just so happen that the general things Bernie wants versus the general things Hillary wants would give more net positives to blacks and browns.
Hillary helped fund the new conservative democratic bloc. They are directly responsible for a lot of the ill shit that is happening in America and abroad today.
