The Black Lives Matter is an international movement that opposes violence and systematic racial discrimination against African Americans. The movement regularly organizes protests and marches, where it declares its indignation and the unacceptability of police brutality against African Americans as well as other issues of racism including the systematic injustice in the legal and economic systems of the United States. Besides this, the movement is widely represented online. It was founded in 2013 when a police officer was acquitted by the court after killing an African-American 17-year-old young man Trayvon Martin. The three prominent activists referred to as the co-founders of the movement are Alicia Garza, Patrisse Cullors, and Opal Tometi. Today, the movement is the topic of a heated social debate. Many criticize it for its aggressive tactics and emphasizing the importance of just one group of the population. The All Lives Matter and the Blue Lives Matter (for police officers) movements were established by activists as responses to Black Lives Matter. However, if the anti-black racism in the United States is reviewed, including the systematic economic and social discrimination, it can be argued that the Black Lives Matter movement’s confrontational discourse and philosophy are justified by the decades of oppression and unequal treatment as well as continuing discrimination against African Americans in the American society. The Black Lives Matter movement has been heavily criticized by various individuals and groups in the United States and other countries. The major point of the criticism is that the movement’s slogans, activities, ideas, and agenda emphasize the importance of just one portion of the population while disregarding the rest of it. The opponents and the critics of the movement have claimed that it overlooks the significance of other people, e.g. white police officers, who are the targets of the movement’s reproof, although they often fall victims to violence, too. Even some prominent members of the African-American community, such as civil rights activists Chip Murray, Najee Ali, Earl Ofari Hutchinson, and Barbara Ann Reynolds have made critical statements on the tactics and approaches of Black Lives Matter claiming them to be aggressive, divisive, and confrontational. Barbara Ann Reynolds compared it to the Civil Rights Movement of the 1960s and stressed that the movement led by Martin Luther King Jr. was nonviolent and it managed to gain support by acting in a respectable manner and to change the legislation by conveying a message of unity. The Black Lives Matter movement differs dramatically from these methods. Another point of criticism was the anti-police position of Black Lives Matter. When two police officers were killed in Brooklyn, New York, in 2014, officials and activists started the Blue Lives Matter movement. The movement was critical of Black Lives Matter because of the latter’s anti-police messages and agenda and exaggerating the problem of police brutality in the United States. The matter of trust for law enforcement authorities is an important social issue because when police officers are feared, it undermines a fundamental principle of a society—the principle of security. Such fear can be ignited and boosted by media coverage and unbal
