The statement 'No, you are.' is a brief retort in response to an accusation made by @StephenM. The original statement by @StephenM involves a serious accusation regarding the counting of undocumented immigrants in the census and its impact on democracy, which constitutes public discourse. However, the response 'No, you are.' does not substantively engage with the public issue or provide any analysis or argumentation. It is more of a dismissive retort rather than a contribution to civic dialogue.
