My partner was a stateless person for the first twenty years of her life and had to flee her country after it was ravaged by American military forces -- she doesn't see the point in voting for Biden or Bloomberg because she feels they won't fundamentally alter the course of what America is and what it does to people of color at home and abroad, either in the short term or the long term. That their election would only provide an aesthetic change that allows people to go about their day as normal while America still commits atrocities at a similar rate.

I know it's easy to blame this on "white brocialists", but the more radicalized portion of Sanders supporters tend to be a pretty diverse group with a diverse amount of reasoning behind their aversion to some or all of the other Democratic candidates.
