If as you are saying Bob and Lucifer believe there is more of a problem with teenage sex in religious states I would think the data to look at would not be pregnancy rates but the number of teens who are sexually active as this would be considered a "sin" among the more religious population. Pregnancy would be the result of those not practicing safe sex. I did not see a table for this rate (maybe I missed it). Sexual activity should include all forms of sex not just intercourse.
Reports have indicated teens who sign chastity pledges are more likely to engage in oral and anal sex believing they are not breaking their pledge.
I agree. The author of the referenced piece, Bob and Lucifer are trying equate religiousity and teenage sex or pregnancy or births to somehow prove that religious folks are hypocritical. But, as noted in my posts and your post, you cannot draw such a conclusion from the data presented.
Not even a good try on their part.
