> It is illegal to shout "Fire" in a crowded theatre. Why? Because it is common sense that it is dangerous, can cause lives to be lost. Actually it's not, but it's a super common misunderstanding and I'd guess that most people familiar with the phrase believes it is, unfortunately. From Wikipedia: > The case was later partially overturned by Brandenburg v. Ohio in 1969, which limited the scope of banned speech to that which would be directed to and likely to incite imminent lawless action (e.g. a riot). It's not that there are no constitutionally bannable types of speech, it's just that yelling "fire" in a crowded theatre isn't one of them. I don't know if this ruling affected individuals' ability to sue charlatans for damages arising from believing their lies (e.g. "there is no virus" or "the vaccine is actually more dangerous") but I'm guessing there's a really high threshold to cross.
