Censorship, the invasion of privacy, and interference of opinions are human rights violations according to the ALA. In response to violations of human rights, the ALA asserts the following principles:  Youth for Human Rights International (YHRI) is a non-profit organization founded in 2001 by Mary Shuttleworth, an educator born and raised in apartheid South Africa, where she witnessed firsthand the effects of discrimination and the lack of basic human rights. The purpose of YHRI is to teach youth about human rights, specifically the United Nations Universal Declaration of Human Rights, and inspire them to become advocates for tolerance and peace. YHRI has now grown into a global movement, including hundreds of groups, clubs and chapters around the world.
