O'Malley I can understand, given his record in Baltimore. But what exactly is their issue with Sanders?
This is what I really don't understand. Did they not see his speech that he made to the SCLC? That was one of his best speeches. It took maybe 10-15 minutes to read it on his website. I don't want to beat a dead horse, but he was active as far back as the 1960's in the civil rights movement. A lot of blacks would be helped by his economic ideas because they are disproportionately poorer on average. He has denounced over-policing and would consider legalizing marijuana, which would help keep people, especially black youth, out of prisons. He supported Jesse Jackson in 1988. I'm just not sure what he's supposed to do to get their support other than making BLM the only issue of his campaign.
Looking at O'Malley's record in Baltimore is not pretty. Look at the riots earlier this year. Why aren't BLM protestors going after him more?
You don't seem to understand the ethos of this movement. These people don't care about Bernie Sanders' participation in the civil rights movement because Bernie Sanders is inherently an oppressor. He was an oppressor in the womb and nothing that he can do, including standing in the corner staring at his shoes while his own rally is coopted, can change that.
