Nonviolent resistance (NVR), or peaceful act, is the practice of attaining objectives, for instance, social change via economic or political non-cooperation, figurative demonstrations, civil defiance, or other techniques while being peaceful. The key advantage is that nonviolent activists have the ethical high ground; they disclose their violent challengers' cruelty. The disadvantages are that peaceful activists can be mistreated or even murdered by fierce rivals.
Militant denotes energetically active, antagonistic, and destructive, particularly in favor of a cause, as in "revolutionary and political agitators." The key positive aspect of the militant movement is that being part of collective action or cause has continuously been an assurance of individuals keen to go through personal sacrifices, and joining such a group leads to mental and social rewards. The main disadvantage of militant movement is that it leads to extremism, which leads to loss of life and destruction of properties such as Al Qaeda in the Middle East and the Sinaloa Cartel in Mexico.
I would take part in nonviolent action because it suggests an obligation to use peaceful and innovative means such as protest and persuading, activism, civil disobedience, strikes, boycotts, education, and non-cooperation to fight back fierce forces to impact and inspire social change.
