Cameron's publications have been cited as support by some groups who oppose same-sex marriage and allowing homosexuals to become foster or adoptive parents, including the Traditional Values Coalition. Cameron testified in the case "Baker v. Wade" (1985). In 1992, Gale Norton, then the Attorney General of Colorado, employed Cameron as a consultant when defending a law preventing the extension of civil rights legislation to homosexuals. Cameron's testimony went unused, and the law was struck down by the Supreme Court. Cameron campaigned against a gay-rights initiative in Maine in 2000, testified in favor of the failed Virginia Anti-Gay Adoption Bill in 2005, and opposed a 2007 Colorado bill intended to allow cohabiting couples to adopt. He was tricked into appearing in Sacha Baron Cohen's 2009 mockumentary film "Brüno".
