In reply to:
The statement '@RIKKISCHLOTT Thanks Rikki!' is a brief expression of gratitude in response to a previous tweet promoting a TED Talk by Andrew Yang. The content of the original tweet by @RIKKISCHLOTT addresses a substantive public issue regarding the flaws in the American electoral system and suggests a solution, which constitutes public discourse. However, the reply itself, expressing thanks, does not engage with the public issue substantively but merely acknowledges the sharing of the information. Therefore, the reply does not constitute public discourse as it lacks substantive engagement with the public issue discussed.
