Privacy is a basic human right. Yet, for 200-plus years, Americans have tolerated "morals laws" that told them who we could marry and what sexual positions they were allowed to enjoy.
You couldn't marry outside your "race" in every state until 1967. Oral and anal sex were illegal until 2003. But morals laws are doomed. Courts are throwing the government out of our bedrooms.
Puritanism is dying hard. Some people still want the police to regulate our sex lives. In his dissent to the 2003 Supreme Court decision striking down anti-sodomy laws in Texas, right-wing Justice Antonin Scalia complained that the SCOTUS had undermined "the ancient proposition that a governing majority's belief that certain sexual behavior is 'immoral and unacceptable' constitutes a rational basis for regulation."
