But going back to the understanding of birth control, or even sex ed - I went to a school that had a huge population of homeschooled and/or kids who grew up in oppressively conservative Christian households. At least one girl was having unprotected sex with her boyfriend, but she was never even taught about sex. Her boyfriend convinced her that sex was 'snuggling' and so she would just tell people she was going to 'snuggle' with her boyfriend.
Even my wife, until high school, believed that sex was physically impossible unless you were married.
There's a very significant segment of the population who doesn't have adequate sex ed. nor has good access to contraception. And even if they do, they may not be able to use it. And even if they understand how to use it, they may be ostracized and/or punished for doing so.
That's the biggest damn hypocrisy of the anti-abortionists. It's mostly the same people who work to ban abortions who also work to ban sex-ed and access to contraception - two things that actually drive abortion numbers down.
As adults, it's easy enough to see (if you're willing to hear the arguments) why sex is used as control over people. You can look back through hundreds or even thousands of years of history (ignoring the shit that goes on today) to find mounds of evidence of how sex is nothing more than a tool to control teens and women.
But when you're a child up through (and often well past) young adult being raised in that environment (and mine wasn't even that bad, just a conservative household & private school), it's not even talked about often until high school, depending on how many secular friends you might have. And then when it is talked about, it's with the sole intent to shame and demean you for even thinking that you might want to become sexually active. Of the few sex ed courses I had the luxury of attending in school, the messaging wasn't how to use contraception or how to communicate with a partner about wants/needs or how to recognize abusive behavior. It was abstinence is the only way/girls are whores (lightly veiled) if they have sex before marriage, porn is a sin, contraception is a no-no, and abortion is off the table.
In fact, if any of it occurred in a religious context, the messaging was extremely clear that you were going to be damned for all eternity if you had sex outside marriage, had lustful thoughts, used porn, used contraception, had an abortion, or a bunch of other crap that I've chosen to block out.
Further and worse, high schools and colleges within a days' drive of DC (and especially Catholic schools) strongly encourage and subsidize kids to go to DC and participate in the march for life. It's a badge of honor. The messaging is highly incongruent - spew shame and hate towards those who choose to have an abortion while also not creating a healthy dialogue over this fundamental aspect of human biology.
