Why did they go public? Because they have no shame. Why do they have no shame? Because our society, lead by the courts, has decided that nothing connect with adult sex is shameful.
In 1986, when the Supreme Court upheld a Georgia law against homosexual sodomy, the majority wrote: "And if [the pro-gay-sex position] is limited to the voluntary sexual conduct between consenting adults, it would be difficult, except by fiat, to limit the claimed right to homosexual conduct while leaving exposed to prosecution adultery, incest, and other sexual crimes even though they are committed in the home. We are unwilling to start down that road." Bowers v. Hardwick, 478 U.S. 186, 196 (1986).
Then, just 17 years later, the Court started down that very road when it struck down a similar law in Lawrence v. Texas. "The petitioners are entitled to respect for their private lives," Justice Anthony Kennedy wrote for the court's majority. "The state cannot demean their existence or control their destiny by making their private sexual conduct a crime." Justice Scalia dissented, pointing out how the decision would invalidate laws against all other kinds of sexual conduct between consenting adults: "State laws against bigamy, same-sex marriage, adult incest, prostitution, masturbation, adultery, fornication, bestiality, and obscenity are likewise sustainable only in light of Bowers' validation of laws based on moral choices. Every single one of these laws is called into question by today's decision; the Court makes no effort to cabin the scope of its decision to exclude them from its holding. See [majority decision] at 11 (noting "an emerging awareness that liberty gives substantial protection to adult persons in deciding how to conduct their private lives in matters pertaining to sex"). "
Rick Santorum was pilloried for the following reaction: "If the Supreme Court says that you have the right to consensual [gay] sex within your home, then you have the right to bigamy, you have the right to polygamy, you have the right to incest, you have the right to adultery. You have the right to anything."
Since the State is the new Church for the lemmings, the fact that the State has decreed that it cannot and will not condemn ANY private conduct between consenting adults (and how long with the "adult" qualifier last...) will bring more and more of this kind of filth into the mainstream.
