Good luck with that one
Apparently, the state of Virginia is starting a campaign to discourage men from having sex with underage girls. I'm glad that it's finally getting through to people that female sexuality isn't the cause of all evils in the world and that men who do wrong things need to be held responsible. The vast majority of debate over teenage pregnancy is centered around how exactly do we best oppress teenage girls. Rarely do you hear it even mentioned that sex and birth control decisions are made by two people. And even more rarely do you hear it mentioned that alot of teenage pregnancies are caused by adult men, which means that there is potential for huge power inequities going on, where the girls may not be in the best position to decide what kind of sexual activity will be going on and what kind of birth control will be used.
Still, men who go after teenage girls, especially those who after really young teenagers, probably have serious issues that prevent them from relating to women their own age. These signs don't address their problems and therefore don't address the problem.
By the way, I'm not talking about the non-problem of teeangers having sex with each other in a normal way that occasionally causes legal flare-ups, like say an 18 year old boy and his 16 year old girlfriend. That shouldn't be against the law. In fact, if we could learn to be less alarmist about normal teenage sex, it would be easier to address the very real problem of grown men in their 20's and 30's who pursue young teenagers of 12 and 13 years old.
