A vocal critic is someone who openly expresses their opinions, often in a negative manner. They are not afraid to speak out and share their thoughts about something or someone, even if it means being critical. This term can be used both positively and negatively depending on the context of the criticism. For example, a vocal critic could be an advocate for change who is willing to voice their dissatisfaction with certain issues in order to bring attention to them and encourage improvement. On the other hand, they may also be seen as someone who complains frequently or is overly critical without offering any constructive solutions.
