Again, does NOBODY know what the first amendment covers???
If you yell FIRE in a crowded theatre (misinformation) that is not covered by the 1st amendment[1]. Please stop talking confidently about something you don't understand.

Edit: Schenck v. United States was largely overturned by Brandenburg v. Ohio but not completely, only limiting the scope. There are also many other examples that could be used to show that spreading misinformation is not blanket covered by 1a (defamation for example).
