No internationalization of family & domestic issues
The internationalization of domestic issues appears in a host of social issues: abortion; family law and relationships between parent and child (the Convention on the Rights of the Child); and discrimination based on gender
(the Convention on the Elimination of All Forms of Discrimination Against Women), race (The UN Committee on the Elimination of Racial Discrimination), or disability (Convention on the Rights of Persons with Disabilities).
The issue here is not, for example, appropriate protections against discrimination, but who should decide such questions.
Should it be American citizens operating under our Constitution, or international agreements with nations that care little about fundamental freedoms or the importance of democratic debate? This is where the rubber truly meets the road on sovereignty.
