The statement 'We’re not bringing a chisel. We’re bringing a chainsaw.' is metaphorical and lacks context to determine its engagement with public issues. Without additional information about the website 'x.com' or the context in which this statement is made, it is difficult to assess whether it constitutes public discourse. The statement could imply a drastic or aggressive approach to a situation, but without knowing the specific public issue or debate it addresses, it cannot be evaluated as public discourse.
