So essentially, you're just pretending that people will act irresponsibly instead of teaching responsibly, which is what I've been saying all along.
No, what I'm saying is just teaching people not to do something is short sighted and ignores reality. People, young and old, will rebel. No matter how strict of an upbringing you have. Especially teenagers, who will try out their peer's morals. Which is perfectly normal behavior and practically essential to them becoming independent people.
And how the hell does placing emphasis on personal and your partner's safety standards when having sex with your boyfriend or girlfriend equal not being responsible?
I mean look at history. The 1700s were very strict about social etiquette. But then again, you had the libertine movement. The 1800s were very rigid and proper. So you had the Decadents/Aesthetics like Oscar Wilde. The 1900s had the Suffragettes, who were often seen as almost obscene. The 1940s to 50s saw Greasers and the Rock and Roll rebels. 1960s and 70s were the Hippies, 80s hardcore Punk. 90s saw grunge and other counterculture movements and now you have those hipster types. People will rebel, they will reject societal standards to a certain degree (some more than others) for a multitude of reasons and they will come up with their own way of doing things. Especially among the youth.
You can't come at teenagers like they're children. They are on the cusp of adulthood and they need to be taught things about the world around them. One of those things in today's world is how to have safe sex. It doesn't matter if you're marrying your partner, you will need to know that sort of stuff to be on the safe side. I mean god help the poor ******* who was denied comprehensive safe sex and then raped, for example. How are they supposed to know the symptoms of an STD? How are they supposed to know that orgasms are biological functions and do not need consent? How are they supposed to know that what their friend told them on the playground about not being able to get pregnant if you pull out is factually inaccurate if they didn't have some authority correct such a misconception?
It's far far better to have experts (or at the very least trained teachers) teach teenagers about sex than them learning it from pornography and what their friends are telling them!!
Comprehensive Safe Sex, apart from you know that whole teaching thing that schools are supposed to do is actually more like a fail safe. No one is saying that there aren't teenagers who will remain abstinent till marriage. But there will be teenagers as well as adults who will do what their biological instincts are crying at them to do. That is part of being a human. So you teach people how to be safe BEFORE they are sexually active. Hence why you teach it to young teenagers in the first place! Teach it to them in Uni and it may be too late for some.
It's this thing called being practical.
Then of course comprehensive sex ed also covers things like consent, frank discussions about sexuality in order to promote healthy viewpoints of sex, consent, puberty, different ways to contract STDs, realize coercive tactics and how to avoid them, how to protect oneself at a party and a million and one other things that are pretty common in adolescence in general.
I mean hell, I remember being in year 9 and we had this class called "Life Skills" or LISK for short. It taught us things like how to spot the signs that your drink has been spiked, what to do if a friend is passed out (roll them on their side so they don't choke on their vomit) always watch your drink in public or at private parties, never drive drunk etc etc. This wasn't teachers telling us that we should go out and party, they were arming us with knowledge so that IF we ever were in such a situation we might make a better informed decision than if we didn't know of such things and made a decision in ignorance.
Or are you suggesting we promote ignorance and then feign shock when something bad happens due to said ignorance?
