A protester is an individual who publicly expresses their disagreement or support for a particular cause, often through demonstrations, rallies, or marches. Protesters aim to raise awareness about social, political, or environmental issues and advocate for change. They may carry signs, chant slogans, or engage in peaceful activities to convey their message. Protests can occur in various forms, including peaceful gatherings or more organized movements. Notable examples of protests include the Civil Rights Movement in the United States and the Climate Strikes led by young activists. Protesters play a crucial role in shaping public opinion and influencing policy decisions.
