A/70/321 racism, racial discrimination, xenophobia and related intolerance, especially in promoting the principles of tolerance and respect for 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 enabled to address crimes motivated by racist, xenophobic, anti-Semitic or homophobic biases by means of 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 (A/HRC/23/24, para. 34). 85. The Special Rapporteur welcomes the organization of awareness-raising activities, such as cultural events, festivals, conferences, seminars, competitions, exhibitions, research work and publications as well as information campaigns and other events aimed at providing a space for intercultural dialogue and interaction, which contribute to the building of a society based on pluralism, tolerance, respect for cultural diversity, multiculturalism and non-discrimination (A/HRC/29/47, para. 53). The Internet and social media 86. The Special Rapporteur reiterates his concerns regarding the increased use of the Internet and social media by extremist political parties, movements and groups to promote and disseminate racist content (A/HRC/26/49 and Corr.1). He calls upon States to take all opportunities, including those p rovided 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 those ideas and biases and strengthen freedom of expression and freedom of assembly and association, which play a crucial role in promoting democracy and combating racist and xenophobic ideologies based on racial superiority (A/HRC/23/24, para. 35). Sports 87. The Special Rapporteur calls upon States to strengthen measures to prevent racist and xenophobic incidents at sports events. As he indicated in his report to the General Assembly in 2014 (A/69/340), he 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 sports events to promote the values of tolerance and respect. He recalls paragraph 218 of the Durban Programme of Action, in which States, in cooperation with intergovernmental organizations, the International Olympic Committee and international and regional sports federations, are urged to pursue the efforts against racism in sport, in particular by educating youth through sport practised without discrimination of any kind and in the Olympic spirit of human understanding, tolerance, fair play and solidarity. 15-13793 19/21
