> if the debate was about ISIS propaganda?
Google recently deleted the entire account of someone who had videos of vehicles in the Middle East, claiming it was extremist content [0]. He was a historian who was cataloging how vehicles are used and modified in military operations across the globe. But google’s bots (which are probably pretty similar to YouTube’s) classified it as extremist content.
So I disagree with the premise of your argument — that we’d all support the automatic removal of “ISIS propaganda”.
