[Pro-choice] The Constitution protects various rights that are not specifically mentioned, but are derived, via Supreme Court interpretation, from other rights. Examples of this are the right of free association and the right to distribute printed material. The constitutional right of privacy has been interpreted repeatedly to include matters of marriage, family and sex, specifically “the right to be free from unwarranted governmental intrusion into matters so fundamentally affecting a person as the decision whether to bear or beget a child.” [Anti-Choice (RTL)]
