It’s not just about facts: Democrats and Republicans have sharply different attitudes about removing misinformation from social media::One person’s content moderation is another’s censorship when it comes to Democrats’ and Republicans’ views on handling misinformation.
Technically, it’s causing a panic that’s illegal. Yelling fire is not. https://law.stackexchange.com/questions/28853/is-it-illegal-to-yell-fire-in-a-crowded-theatre
Different states have different laws, of course, and I am not a lawyer, I just googled if it was actually illegal. Don’t actually go yelling fire in a crowded theater.
Right, it’s perfectly fine to alert people to a fire if there actually is one. Yelling “fire” when there isn’t one will be generally interpreted as causing a panic.
