For example ...
Suppose you have a good medical insurance plan at work, and you also have a close friend of the same gender (or either gender, for that matter) who is uninsured. There's nothing that prevents the two of you from "getting married" just for the sake of getting him insured through your employer's group plan.
There are probably dozens of similar situations where there are legal and financial advantages to being "married" to someone even if you have no romantic interest in him.
If the Federal government wants to turn the institution of marriage into a farce, I can play that game too.
Also think gays are going to have huge legal bills from marriage.
1. Divorce. Extremely expensive. Basis for divorce is adultery. Do gays play by those rules?
2. Palimony. Gays living together for years in California. Now that’s common law marriage.
I’m not sure this is the battle to fight at this point.
