How did Justice Harry Blackmun’s dissent interpret the privacy issue in Bowers v. Hardwick?

In his dissent in Bowers v. Hardwick (1986), Justice Harry Blackmun argued that the majority fundamentally distorted the case by focusing narrowly on "homosexual activity" rather than the underlying constitutional principles at stake.1

Blackmun contended that the case was not about establishing a specific "fundamental right to engage in homosexual sodomy," just as previous privacy precedents were not about rights to watch obscene movies or place bets from telephone booths. Instead, he framed the issue through the lens of the "right to be let alone," which he described as "the most comprehensive of rights and the right most valued by civilized men".1

Ultimately, Blackmun asserted that the Court’s refusal to recognize this right ignored the fundamental interest all individuals possess in controlling the nature of their own intimate associations. This perspective emphasized that the protection of privacy extends to the personal autonomy of individuals in their private lives, a view that was later vindicated when the Supreme Court overturned Bowers in Lawrence v. Texas (2003).1
