It’s not “embracing Trump”, that’s what liberals like to frame it as for rhetorical effect. Calling it accelerationism is just willful ignorance towards what the intentions of the approach are. It’s a strategy oriented around timescale that is more than just this election (in stark contrast to the alarmist “Most important election of our lifetime” rhetoric of liberals) because there will be more elections and unconditional subservience to the dems in this election will encourage their lurching still further to the right in future elections.

The purpose is to make the Democrats choose between concessions to the left or letting the Republicans win. It’s not difficult to understand.
