>>>I guess the fact teen pregnancy rates are the highest in states with abstinence-only education eludes these idiots.

>The paper you quote is using 2005 figures: latest US figures report teen pregnancy rates down 42% since the implementation of these programs and the lowest teen pregnancy rates since 1972. The boot may be on the other foot if people want to equate correlation with causation. ;-)

I couldn't find any recent data comparing pregnancy rates correlated to type of sex education. This, from 2005, shows higher levels in states which emphasize abstinence:

Snip:
After accounting for other factors, the national data show that the incidence of teenage pregnancies and births remain positively correlated with the degree of abstinence education across states: The more strongly abstinence is emphasized in state laws and policies, the higher the average teenage pregnancy and birth rate.

>FWIW, personal view: promoting abstinence often lurches towards withholding information, which creates an ethical issue and seems impossible in the internet age anyway. Might as well seize the opportunity to get in a few important issues while kids are still prepared to listen. E.g. the fact that most oral and throat cancer these days is associated with multi-partner oral sex that is becoming normalized in some teen cliques. They're less likely to google that than the flavor of a cond*m so it's our job to make sure this sort of information is available for their informed choice.
