What a man and the woman he's married to do in the privacy of their own home is their business. It always has been. (It's even sanctioned in the bible)
Homosexual behavior should be illegal wherever it takes place, just as murder or child molesting is illegal under any circumstances. It has been illegal for most of our history and should be illegal again.
This is not an equal protection issue, and the ruling by the court was a tragedy and wrong. People who practice homosexual behavior have and had all the same rights as I do. They had the right to marry same as I. The thing they don't have the right to do is to commit illegal behaviors such as child molesting (or in a rational world, homosexual behavior).
