Such persons, when they attack the parents seeking to treat their child's autism disorder, are advocating against the UN declared rights of that child.
Such persons are practicing false advocacy.
Declaration of the Rights of the Child
Proclaimed by General Assembly resolution 1386(XIV) of 20 November 1959
Whereas the United Nations has, in the Universal Declaration of Human Rights, proclaimed that everyone is entitled to all the rights and freedoms set forth therein, 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,
Whereas the child, by reason of his physical and mental immaturity, needs special safeguards and care, including appropriate legal protection, before as well as after birth,
Whereas the need for such special safeguards has been stated in the Geneva Declaration of the Rights of the Child of 1924, and recognized in the Universal Declaration of Human Rights and in the statutes of specialized agencies and international organizations concerned with the welfare of children,
Whereas mankind owes to the child the best it has to give,
The General Assembly
The child shall be entitled from his birth to a name and a nationality.
The child shall enjoy the benefits of social security. He shall be entitled to grow and develop in health; to this end, special care and protection shall be provided both to him and to his mother, including adequate pre-natal and post-natal care. The child shall have the right to adequate nutrition, housing, recreation and medical services.
The child who is physically, mentally or socially handicapped shall be given the special treatment, education and care required by his particular condition.
The best interests of the child shall be the guiding principle of those responsible for his education and guidance; that responsibility lies in the first place with his parents.
The child shall in all circumstances be among the first to receive protection and relief.
The child shall be protected against all forms of neglect, cruelty and exploitation. He shall not be the subject of traffic, in any form.
The child shall not be admitted to employment before an appropriate minimum age; he shall in no case be caused or permitted to engage in any occupation or employment which would prejudice his health or education, or interfere with his physical, mental or moral development.
The child shall be protected from practices which may foster racial, religious and any other form of discrimination. He shall be brought up in a spirit of understanding, tolerance, friendship among peoples, peace and universal brotherhood, and in full consciousness that his energy and talents should be devoted to the service of his fellow men.
