&gt; So? So is calling people &quot;rapists&quot; (without proof or conviction), but we don&#x27;t outlaw it.<p>Falsely calling someone a rapist is unlawful and subjects the person doing it to legal consequences many places (including most jurisdictions in the US); where the burden of proof is on demonstrating the truth or falsity of the statement, whether and in what circumstances a good-faith mistake of fact will excuse the offense, etc., vary from jurisdiction to jurisdiction, but it is certainly not a matter on which it is some widely accepted principal that people are free to make false claims without consequence.
