I have a fairly progressive friend group, and they still have problem with accelerationism in many contexts. They're not the ones being hauled off to camps when they talk about more ICE getting white people to be so inconvenienced they finally vote to abolish it.

This mindset of I want to make a statement in a way that disregards the effect of how that statement is made on marginalized communities is still alive and well. You want the Dems to change, then you need to do actual leg work to support and lift up opposing candidates within the party. There's no easy way out of this.
