Dissidents are individuals or groups who oppose or challenge the policies, practices, or ideologies of a governing authority or dominant social norms. They often advocate for change, expressing their views through protests, writings, or other forms of activism. Dissidents can be found in various political, social, and cultural contexts, and their actions may lead to significant societal shifts. Throughout history, many dissidents have faced persecution or repression for their beliefs. Notable examples include Nelson Mandela, who fought against apartheid in South Africa, and Aung San Suu Kyi, who advocated for democracy in Myanmar. Their struggles highlight the risks and importance of standing up for one's convictions.
