The statement 'I’ll be ready for our rematch when you are, HJ.' accompanied by an image of a group of young people with an older man, who appears to be in a position of authority or respect, does not constitute public discourse. The statement seems to be a personal or playful challenge directed at an individual named HJ, likely in a friendly or competitive context. The image, showing a moment of farewell with the caption 'Bye, Mr. President!' suggests a casual or affectionate interaction, but does not substantively engage with public issues, policies, or societal debates.
