Silent protest
A silent protest is an organized effort where the participants stay quiet to demonstrate disapproval. It is used as a form of civil disobedience and nonviolent resistance that encourages voicing out different opinions through certain acts such as not showing support to a certain product, attending mass parade, having symbolism, and educating and encouraging other people to join the protest. This aims to support and resolve different matters related to inequality, peace making, and nation leadership problems. Examples
