Progress is always already happening: by definition, we are in the midst of progress, making it a bit oxymoronic to label yourself as being for something you can’t stop or start.
This pedantic insight reveals that Progressives are only for a specific type of movement in a singular direction, which must be spurred on or accelerated. This requires an ideology mapping out the future utopia, which can be used to direct the morally fervent. This type of religiosity is also on the right but progressing backward: they are applying the brakes for a return to known dangers/ills rather than theoretical expansive equality.
The problem with claiming that “the arc of history” bends progressively or that you need to be on “the right side of history” is that if progress is already progressive, why fight so hard? It is not happening fast enough, so we must accelerate, which creates the conditions for an ideological tug-of-war to slow down the change, burning energy and relationships at both ends.
