This has got to be one of the stupidest scientific (if you can call it that) debates ever. A vaccination will not encourage a teenager to have sex. Nothing encourages teen girls to have sex more than teen boys or other teen girls who have already done so. Even if your daughter’s a huge slut, do you want her to get cancer for it? This is the same party that thinks graphic sex education and contraception information encourages promiscuity. Hormones cause promiscuity. That and ‘being cool’ with your group of friends. Nothing’s more influential in a teenager’s life than their friends opinions, usually. Your sex-ed textbook, or whatever they call it these days, is probably close to last on the list of things that would influence that decision.
