225 Same sex households

According to the census 2000, 1.6% of all households are same sex couples, 4.5% are unmarried opposite sex couple households, 25.8% of households are one-person, and 52.8% of households are married couples. There's a smattering of households of blood relatives, not married, and a few "other." I'm a little puzzled that there is such a noisy clamor for gays to marry, if they apparently aren't even living together now supporting each other with joint bank accounts, joint mortgages and wills designating each other beneficiaries, unless there just aren't very many gay and lesbian couples. And how many of those 1.6% even want to marry? Has anyone polled the group to see who is fine with the status quo? Has there been a count of those who enjoy the lack of ties and responsibilities, who don't want to share their wealth, who want to move on when life gets dull?
