I don't think that analysis of why Establishment Dems keep losing is advocacy for accelerationism. Most of the people who sit out of elections are not the kinds of people to post on the internet in political threads. If we want to reach the people on the who have become politically apathetic, the most effective method would be a top-down approach where the politicians and leadership change their positions and how they advertise the party.

We already know why these people don't vote. Yelling at them to vote hasn't worked for a decade, so we should try something else.
