This story about different sexual norms between so-called red states and blue states is interesting. It relies at length on the scientific studies of Mark Regnerus, a sociologist at the University of Texas at Austin. While I was at Texas, I had the opportunity to listen to Prof. Regnerus up close a couple times. He is a very good sociologist.
From the story:
Social liberals in the country’s “blue states” tend to support sex education and are not particularly troubled by the idea that many teen-agers have sex before marriage, but would regard a teen-age daughter’s pregnancy as devastating news. And the social conservatives in “red states” generally advocate abstinence-only education and denounce sex before marriage, but are relatively unruffled if a teen-ager becomes pregnant, as long as she doesn’t choose to have an abortion.
