More broadly, "support" for a camp usually amounts to rhetoric and protest that yield no "concrete gains", because few campists hold political power and each "camp" is a massive entity. A "preoccupation" with "abstract" questions of foreign policy "has been historically corrosive for the left, leading to bitter fights over precisely those issues which we are least able to affect".
I would call Stalin committing genocides and exiling Russian POWs to the gulags "horrific," not "sad."
Yes, Daddy! Airbrush me out of one of your photographs!
