"protections of the nuclear family is a violation of basic Human Rights".
The thing is, the nuclear family usually consists of Father, mother and children all living in the same household. Once the children leave home, they set up their own "nuclear" family by getting married and raising children. JWs do not shun members of the nuclear family, i.e. if a member of the family lives in the same household, they will not be shunned. Husband and wife are not shunned, and neither are children who live at home.
