More accurately, I believe it's fair to say your description is a steelmanned version of "the left's" argument. I happen to be in very high agreement with what you've said.
Some issues I see with this perspective:
- a very small percentage of people, regardless of where they fall on the political spectrum, think about these matters in anything approaching the level of complexity displayed in your comment. This thread is absolutely full of people who seem to have lost the ability to distinguish between reality itself and an extremely lazy interpretation of reality. I can appreciate the frustration that's brought them to this point, but the ability for a small percentage of people like you to skillfully articulate a steel-manned version (that may not actually be technically accurate let's not forget) of the beliefs of an emotional mob doesn't give me a lot of comfort
- not all powerful actors are behaving in a completely honest or as well thought out manner, or may believe that censorship "overreach" is strategically justifiable, from an "ends justify the means". And this may very well be a reasonable and even correct belief, at this snapshot in time, and under these particular circumstances - but what about the future? What if we get another Trump-style leader in the future exploits well-intended limits of free speech toward an undesirable end?
- by not extending any effort towards understanding the real and extremely psychologically complex motivations that are actually behind the emotional lashing out of people (that we all know very well happens with humans, that can be observed throughout history, and on this very forum), often along "racist" lines, those who propose to curtail free speech may be acting in an overly enthusiastic manner (not to mention, if people can't be bothered to even consider calming down and making a serious effort to understand what is actually going on, why should I trust they have the mental capacity to make wise decisions on something as important as free speech?)
The world is incomprehensibly complex, and getting worse at a rapid pace. I think extreme caution is warranted on any matters related to something so fundamentally important as free speech. If some of these ideas are really so bad, why can good ideas not win out in the marketplace? I have this constant feeling that there is a lack of serious effort, and that there are often not-easily-seen reasons why such an effort cannot be made (Thomas Frank, Jonathan Haidt, and Mark Blyth would be a few people worth listening to if one was interested in starting to get some depth in this perspective).
