I don't know why I need to explain this to people. I guess it's because I allow stupid on my feed.
Tim Walz didn't use the word "disinformation". Tim Walz didn't talk about "defamation". Tim Walz didn't talk about lies or slander.
Tim Walz said -- more than once -- that misinformation isn't protected speech.
That's absurd.
That's to say that, if you honestly get something wrong, it's okay to get the government involved. That's to say that the government gets to decide what is right and what is wrong, and punish you if you say something that the government decided was wrong.
That's not what the First Amendment is about. You're legally allowed to lie -- most of the time. You're definitely allowed say things that are wrong. You should be allowed to say things that are wrong.
