https://en.wikipedia.org/wiki/First_Amendment_to_the_United_..."Attached to the core rights of free speech and free press are several peripheral rights that make these core rights more secure. The peripheral rights encompass not only freedom of association, including privacy in one's associations, but also, in the words of Griswold v. Connecticut (1965), "the freedom of the entire university community", i.e., the right to distribute, the right to receive, and the right to read, as well as freedom of inquiry, freedom of thought, and freedom to teach.[144]"
"The United States Constitution protects, according to the Supreme Court in Stanley v. Georgia (1969), the right to receive information and ideas, regardless of their social worth, and to be generally free from governmental intrusions into one's privacy and control of one's thoughts.[145]"
"As stated by the Court in Stanley: 'If the First Amendment means anything, it means that a State has no business telling a man, sitting alone in his own house, what books he may read or what films he may watch. Our whole constitutional heritage rebels at the thought of giving government the power to control men's minds.'[146]"
