(Article 2. of the Universal Declaration of Human Rights)
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.
The declaration gets a bit costly to live out here because most of us belong to groups that exclude someone else based on one of the categories listed above. To be a citizen of the world means to put the common good over the limited moral isms, economics or politics of any lesser group. Whatever we pledge allegiance to must be harmonious with the whole.
It is not easy to make our peers angry, but we are actually giving them a great gift. We do not love our group less for loving the whole more.
