I'm sorry, but that's ridiculous. I can't fathom a parent who would go through the effort of getting their child on birth control, but not having a discussion about STDs and safe sex.
"Kids" are going to have sex, we should take every opportunity to provide them with a means to do it as safely as possible.
It's simple really. Teenagers tend to take more risks. A possible pregnancy is a good reason to use a condom, as a side effect a lot of stds are also prevented. Removing the pregnancy possibility from the equation removes the need for condom use.
Yes, I know when I was a teenager, getting a girl pregnant seemed like a FAR worse outcome than getting AIDs and dying. I'm not sure if you think teenagers lack basic reasoning skills, or if this is actually your personal reasoning skills being projected onto all teenagers.
