You have a number of points I agree with, but I find other points troublesome. For instance, the costs of censorship are, interestingly enough, also the costs of not censoring free speech. Slowed scientific progress (due to the rise of anti-intellectualism), emotional distress (pretty obvious how some types of free speech cause this), and atrocities (e.g. Charlotesville) could have been avoided through censorship. Those are the material costs of allowing unbridled, "hate group" free speech. On a side note, I am very personally conflicted on this topic. It was strange to read your comment and strongly agree with some statements and then very strongly disagree other statements.
