This is a mistake a lot of states have made.
Abstinence-only (or Abstinence-adjacent) education, while perhaps well-intentioned, hasn't produced the results the proponents thought they would. (the states that tried it ended up with higher teen pregnancy rates)
As it turns out (shocker), horny teenagers will still find ways to have sex once in a while when there's no adult supervision, and restricting education about safe sex practices hasn't done people any favors with regards to that reality.
In the past, I've used the analogy of people with self-control issues surrounding food, and buffets lol.
You take 30 of people with that issue to a Golden Corral, and then simply say "well, weight management is simple....just don't eat" and lemme know how that works out for you.
If people think teens are in anymore control of their hormones than an over-eater is with their appetite, they're dreaming.
Comprehensive sex education is the pragmatic acknowledgment of the reality that "some of these kids are going to hookup at parties when their parents aren't around...it's better if they know how to prevent certain things so that we don't end up with a bunch of pregnant 16 year old or high schoolers with the clap"
Now, to be fair to the other side, do I think some of this is backlash to some of the things that are happening that I think are "over-sexualizing"....Yes. But don't throw the baby out with the bathwater.
A person can object to some of the stuff that's going on while still acknowledging that it's a good idea to make high school students aware of proper condom usage.
