  There is a further issue that has generated disagreement, even among those theorists who believe privacy is a coherent concept. The question is whether or not the constitutional right to privacy, and the constitutional privacy cases described involving personal decisions about lifestyle and family including birth control, interracial marriage, viewing pornography at home, abortion, and so on, delineate a genuine category of privacy issues, or merely raise questions about liberty of some sort. Parent (1983) explicitly excludes concerns about one’s ability to make certain important personal decisions about one’s family and lifestyle as genuine privacy issues, saying the constitutional right to privacy cases focus solely on liberty. Among the others who take this view are Henkin (1974), Thomson (1975), Gavison (1980), and Bork (1990). Allen (1988) defines privacy in terms of access and excludes from her definition protection of individual autonomous choice from governmental interference, which she terms a form of liberty. Yet she refers to this latter protection as “decisional privacy” and says determining its category is purely a definitional point and one of labels. Ultimately she believes interference with decisions involving procreation and sexuality raise the same moral concerns as other privacy intrusions, offending the values of personhood. The Supreme Court now claims (Whalen v.  Roe, 429 U.S. 589, 1977) that there are two different dimensions to privacy: both control over information about oneself and control over one’s ability to make certain important types of decisions.
