What about the uptick from 1999 on?Parts of it is supposed to be the recovering economy, with the rest being that it's become more "fashionable" to get married the last couple of years. Apparently not only the fashion of clothes change through the years.
I have a hard time seeing the effects the article talks about in the statistics and the interpretation the experts are offering (though it's possible they're all ultra-liberal and wouldn't ever point towards homosexual marriage). Lacking convincing evidence, it seems to me Stanley Kurtz first decided what result he thought was appropriate and then interpreted the data to fit the hypothesis.
