Oomis, I guess I can’t blame you for not realizing it but I was actually referring to the Gemara that only when the Nasi does Maaseh Amcha are we commanded Lo Sa’or.
Sure w are Mechuyav to honor the kingdom. But all the above references have nothing to do with privately disparaging of the king. The Tanna in Bava Basra who did not want to condemn Hurdus said that he was afraid to do so.
