Ian, what is this criminal assault you keep talking about? Are you talking about a needle to draw blood for HIV testing?
Exactly how do you "round up" gay males? How could you accurately identify who is who? One obvious way would be to track same sex marriages. Btw, wherever did you get the idea that marriage promotes stabile relationships and monogamy? Not in 2013.
Contrary to what some think, keeping your private life to yourself is not always about hiding in shame. It is often about wisely protecting yourself, especially if you belong to a minority. Something to think about.
One of the reasons my gay aunt would never marry is to protect her privacy, to keep her private life out of the public domain. That is, incidentally, one of the reasons why I wouldn't do it either even though I'm heterosexual.
The 5% want to redefine marriage so they can feel "equal" to everyone else? Have at it! Fool's gold as far as I'm concerned.
In this day and age, it's iffy IMO to tie yourself to another person, legally and publicly through marriage. When you strip away the romance, marriage is a three party contract between you, your partner and THE STATE. The state can change the terms of the contract whenever they please, you and your partner cannot.
If you want to get out of it, lawyers and judges must get involved in your private life. Then there is a public record of your divorce. Meanwhile, it is perfectly acceptable to cohabitate with someone. If it doesn't work out, your names are not linked together for all eternity.
