" Everyone is entitled to all the rights and freedoms set forth in this Declaration, without distinction of any kind, such as race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth or other status. Furthermore, no distinction shall be made on the basis of the political, jurisdictional or international status of the country or territory to which a person belongs, whether it be independent, trust, non-self-governing or under any other limitation of sovereignty." - Article 2, Universal Declaration of Human Rights
Gender roles were an issue across many nations before the implementation of the UDHR. Segregation and discrimination against black people were still a problem here in the United States before the UDHR, while other nations showed discrimination towards minority ethnic groups.
The UDHR helps with “equal protection against any discrimination in violation of this Declaration and against any incitement to such discrimination.” The UDHR included and helped both racial and gender role problems as well as it is included in articles 1 and 2.
