The statement 'The Joe Biden of today isn’t the Joe I once knew.' is a brief, subjective opinion about a public figure, Joe Biden. It suggests a change in perception or behavior of Joe Biden over time. However, without additional context or substantive engagement with specific public issues, policies, or concerns, it does not constitute public discourse. The link to a website with the title 'x.com' does not provide enough information to determine if it leads to substantive content.
