It's not a civil right, but it is a UN human right. So listed on Eleanor Roosevelt's UN Declaration of Human Rights.
The declaration says that all people have the right to opinion and expression. The right to rest & leisure. As well as a standard of living. All mothers and children have a right to special care and assistance. Sounds good so far.
But then you get to Article 29 Paragraph 3. And what exactly does Article 29, paragraph 3 say?
"These rights and freedoms may in no case be exercised contrary to the purposes and principles of the United Nations."
So you have no freedom of speech. No right to proeprty. No freedom of expression. No standard of living. You have nothing if your exercise of said rights interferes with the goals of the United Nations.
