But everybody knows it won't work...

For years those who have argued for sexual abstinence education have been roundly mocked as being out of touch with reality. Such education could not work and would only lead to the growing spread of teen pregnancy and STD's (and that doesn't stand for Doctorate of Sacred Theology).
There must be a sense of vindication to be found then in the article published in the Los Angeles Times reporting on a study showing that abstinence education might be effective.
