The statement '@TEDchris Thank you for the opportunity 🙏🇺🇸' is a response in a conversation thread related to a TED Talk by Andrew Yang discussing U.S. political system reforms. While the original TED Talk content itself constitutes public discourse, this particular response is primarily an expression of gratitude and does not substantively engage with the public issues or policies discussed in the TED Talk. Therefore, it does not constitute public discourse.
