The statement 'God bless Texas 🇺🇸' followed by a link to a broadcast titled 'Vivek Ramaswamy' at the 'America First Policy Summit in Fort Worth, TX' does not constitute public discourse. The statement itself is a general expression of goodwill towards Texas and does not engage substantively with public issues, debates, or discussions. The link to a broadcast, while potentially related to a public event, does not provide enough context in the statement itself to be considered an engagement in public discourse. The content is more promotional in nature, related to an event, rather than a substantive discussion or analysis of public policies or societal issues.
