I’ve been doing a little reading about freedom of speech. More is allowed than I had realized. Public figures are expected to be in the public scrutiny, so even caustic remarks are allowed. Private citizens are more protected from harm to their reputations. Intent is important. A charge of Defamation has to prove that the statements were made with the intent to harm.
“Defamation law tries to balance competing interests: On the one hand, people should not ruin others’ lives by telling lies about them; but on the other hand, people should be able to speak freely without fear of litigation over every insult, disagreement, or mistake… A defamatory statement must be false…People who aren’t elected but who are still public figures because they are influential or famous — like movie stars — also have to prove that defamatory statements were made with actual malice, in most cases. ” nolo.com/legal-encyclopedia/
