Besides, thought, speech, broadcasting and individual rights on private and public spaces are all very different things. At the end of the day, Youtube's platform is their own turf and they ultimately have the physical power to take down whatever the heck they want. Twitter, Facebook and self-hosted wordpress instances all exist as alternatives for Rand Paul, and he'll certainly be back on YT with his same agenda next week. Countries can (and do) hit Youtube with whatever fines they think are appropriate. Rand Paul's constituents will be Rand Paul's constituents. Every party in this saga is basically just doing whatever they want. Where does thought policing fit into any of this?
These couple of sentences came pretty close in my opinion. They read to me as advocacy for the censorship of factual information if you happen disapprove of an opinion the person might hold.
It strikes me as unfortunate that the rationale Youtube gave tried to add legitimacy to their decision by quoting Rand Paul as "evidence" for their case (under the presupposition that a "bad" position must necessarily be supported by factually incorrect arguments), when they could just have said that his anti-mask position goes against CDC guidelines or something along those lines that is easier for a non-expert to verify.
If anything the lesson here is for Youtube to be careful of snake talk that employs half truths as weapons. In other words, if they are not experts enough to determine whether specific quotes are factually true, then don't base decisions on your ability to determine accuracy, and instead defer to the language of the official guidelines.
