That's a huge leap, DTWB. Everything prior to homosexuality can be objectively demonstrated to be harmful to society. They involve the destruction of property, loss of life and/or an imposition on someone else's freedoms. Homosexuality is primarily a private behavior, just as religion is. If one attempts to use the Constitution to regulate private behavior, then you make a case for the secularization of America.

Of course, no one would say that responsibly practiced religion is a threat to the public; I believe the same applies to homosexuality. People who "practice" either can lead honest and productive lives. The imposition of morality is one of the most dangerous things anyone can do.
