What is so awful about the idea that people in the United States might be convinced of something? What does it matter who is doing the convincing? You just don’t like the hypothetical outcome you suggested.
Are you opposed to a Taiwanese propaganda campaign, conducted through a newly popular Taiwanese social media app and directed at convincing U.S. citizens to support Taiwan in the event of an incursion by China? What’s the difference?
I find scary the idea that the U.S. government would try to protect its citizens from anyone’s speech or ideas. The best response to speech you don’t like is to argue forcefully against it; not to suppress it. We can make up our own minds.
I don’t want the government trying to suppress or protect me from thoughts or ideas it thinks are bad.
That's how modern misinformation works, you simply bombard social media networks until the truth is lost in a sea of misinformation.
The difference between the truth and the lie though is that in the end when you actually have to implement policy or predict something, lies tend to eventually collapse in on themselves. Credibility as such emerges for the people/insitutions/frameworks that can consistently predict or give results that reflect reality more. But that can take years or even decades, while gepolitical decisions need to made today.
I don’t want government deciding, on my behalf, what is or is not bullshit — and then taking legislative steps to suppress ideas it doesn’t like.
Is Communism bullshit? Is anti-Anericanism bullshit? How about liberalism? Conservatism? Homosexuality?
Maybe. But those are for me to decide, based on whatever information people want to use to try and convince me. It is not appropriate for government to legislatively suppress ideas or information it thinks is wrong.
If you think otherwise, do you have a problem with the Chinese internet firewall? From their perspective, China is protecting its citizens from harmful, wrong information. You just disagree about their value judgments. (I assume.)
