"Which privacy rights did they find that don't exist in the constitution? Do you argue that no privacy rights exist in the constitution?"
The association of people is not mentioned in the Constitution nor in the Bill of Rights. The right to educate a child in a school of the parents' choice - whether public or private or parochial - is also not mentioned. Nor is the right to study any particular subject or any foreign language. Yet the First Amendment has been construed to include certain of those rights.
Do you disagree with those findings?
