'Mean tweets' is such an empty meaning. Come with examples. It is on paper very easy to break the law via speech. If I post something here about how I want to reward a murder on a certain politician (or want to do it myself), I can guarantee you the police would be involved. And rightfully so.

Freedom of speech is about pre-moderation. It doesn't mean your actions do not have consequences. If you yell fire in a theatre while there is none, you should be held liable. See also the case of Gennaro P. (the Damschreeuwer) who at May 4 of 2010 yelled during two minutes of silence of Rememberance of the Dead.

>doesn't mean your actions do not have consequences

YES IT DOES THAT IS EXACTLY THE POINT

You obviously do not believe in freedom of speech as defined by US law. You are conflating extremely narrow exceptions with broad politically motivated violations of freedom of political speech
