The statement 'YUP. GREAT idea @EMostaque' accompanied by an image with a caption 'What I want to' is conversational in nature. It appears to be an affirmation or agreement with an idea proposed by the individual mentioned in the statement. The image shows a person speaking, and the caption suggests that the person is expressing a desire or intention. The content does not provide enough context to determine if it substantively addresses public issues or policies. Therefore, it does not constitute public discourse.
