Proscriptive laws designed to suppress all forms of nonprocreative and non-marital sexual conduct existed through much of the last millennium. Widespread discrimination against a class of people on the basis of their homosexual status developed only in the twentieth century, however, and peaked from the 1930s to the 1960s. Gay men and women were labeled “deviants,” “degenerates,” and “sex criminals” by the medical profession, government officials, and the mass media.
The federal government banned the employment of homosexuals and insisted that its private contractors ferret out and dismiss their gay employees, many state governments prohibited gay people from being served in bars and restaurants, Hollywood prohibited the discussion of gay issues or the appearance of gay or lesbian characters in its films, and many municipalities launched police campaigns to suppress gay life. The authorities worked together to create or reinforce the belief that gay people were an inferior class to be shunned by other Americans. Sodomy laws that exclusively targeted same-sex couples, such as the statute enacted in 1973 in Texas (1973 TEX. GEN. LAWS ch. 399, §§ 1, 3), were a development of the last third of the twentieth century and reflect this historically unprecedented concern to classify and penalize homosexuals as a subordinate class of citizens. - See more at:
