Not a Lawyer and definitely someone that would love to see Disney get bent over the legal barrel and financial bitch slapped… But Carano has no case and nothing to gain here except publicity with right leaning organizations. Disney gave her numerous chances to walk her comments back and try to educate her to what she did wrong. She refused each time. Disney then terminated her employment and made a standard PR announcement as to why they made the decision they did, something fairly common in the industry.

Defamation would require Disney made untrue comments or statements about her, and her to prove those statements were false or misleading. Since this all happened over public social media, there isn’t any evidence Disney did anything but state facts and amicably as they could inform the public why she would not reprise the character in the future. If there is any comments that would qualify as defamatory Im not aware of any of them.
