In an August 20th column for the Chicago Tribune, Steve Chapman writes,

Opponents of same-sex marriage reject it on religious and moral grounds but also on practical ones. If we let homosexuals marry, they believe, a parade of horribles will follow -- the weakening of marriage as an institution, children at increased risk of broken homes, the eventual legalization of polygamy and who knows what all.

Well, guess what? We're about to find out if they're right. Unlike most public policy debates, this one is the subject of a gigantic experiment, which should definitively answer whether same-sex marriage will have a broad, destructive social impact.

Massachusetts, Connecticut, Iowa, Vermont, Maine and New Hampshire have all decided to let gays wed.

Actually, the "experiment" has been running in Massachusetts for fully 1/2 decade now. Over three years ago I wrote a story, "Christian Right Wrong on Gay Marriage", summing up the apparent non-impact of the then-2 year "experiment". Now, we have 4 consecutive years of data. According to the most recent data from the National Center For Vital Statistics, Massachusetts retains the national title as the lowest divorce rate state, and the MA divorce rate is about where the US divorce rate was in 1940, prior to the Japanese bombing of Pearl Harbor that triggered the US entrance into World War Two.

Provisional data from 2008 indicates that the Massachusetts divorce rate has dropped from 2.3 per thousand in 2007 down to about 2.0 per thousand for 2008. What does that mean ? To get a sense of perspective consider that the last time the US national divorce rate was 2.0 per thousand (people) was 1940. You read that correctly. The Massachusetts divorce rate is now at about where the US divorce rate was the year before the United States entered World War Two.

Yeah, you know why? Because they're wrong. They've always been wrong. Letting same sex partners marry has absolutely no negative effect on heterosexual marriages.

Want to see how gay marriage destroys the family? Come to Massachusetts, where we have the lowest divorce rate in the country, as well as all sorts of other excellent family-friendly statistics. Yeah, we liberals sure are amoral heathens, and any decade now we'll succeed in our mission to destroy the American family (/snark)...
