A/72/291 87. The Special Rapporteur recalls paragraph 13 of the outcome document of the Durban Review Conference (A/CONF.211/8, chap. I), in which the Conference reaffirmed that any advocacy of national, racial or religious hatred that constituted incitement to discrimination, hostility or violence should be prohibited by law, as should all dissemination of ideas based on racial superiority, hatred or incitement to racial discrimination as well as all acts of violence or incitement to such acts. In that regard, the Special Rapporteur calls upon all States to respect the commitments made in the Convention and in the Durban Declaration and Programme of Action, which is a comprehensive framework for action against racism, racial discrimination and xenophobia. C. Education and capacity-building 88. The Special Rapporteur recalls that education remains the most effective means of countering the negative influence that extremist political parties, movements and groups may have on young people. Recalling his thematic report of 2013 (see A/HRC/23/56), he recommends that States recognize the important role of education in combating racism, racial discrimination, xenophobia and related intolerance, especially in promoting the principles of tolerance and respect to ethnic, religious and cultural diversity and preventing the proliferation of extremist racist and xenophobic movements and propaganda. Law enforcement officials and members of the judiciary should also be provided with the capacity to address crimes motivated by racist, xenophobic, anti-Semitic or homophobic biases, through comprehensive and mandatory human rights training, with a specific focus on racist and xenophobic crimes perpetrated by individuals linked to extremist political parties, groups and movements. D. Internet and social media 89. The Special Rapporteur reiterates his concerns regarding the increased use of the Internet and social media by extremist political parties, movem ents and groups to promote and disseminate racist content (see A/HRC/26/49). He calls upon States to take all opportunities, including those provided by the Internet, to counter the dissemination of ideas based on racial superiority or hatred and promote the values of equality, non-discrimination, diversity and democracy, while respecting their obligations under articles 19 and 20 of the International Covenant on Civil and Political Rights. States should adopt measures to counter such ideas and biases and strengthen freedom of expression, which plays a crucial role in promoting democracy and combating racist and xenophobic ideologies based on racial superiority. E. Sports 90. The Special Rapporteur calls upon States to strengthen measures to prevent racist and xenophobic incidents at sporting events. As he indicated in his report to the General Assembly in 2014 (see A/69/340), he further emphasizes the key role of sports in promoting cultural diversity, tolerance and harmony. The Special Rapporteur recommends that States and other relevant stakeholders, such as sports federations, take advantage of such events to promote the values of tolerance and respect. He recalls paragraph 218 of the Durban Declaration and Programme of Action, in which States were urged, in cooperation with intergovernmental organizations, the International Olympic 17-13411 19/21
