Did you read the curriculum? Because, from what I can tell 6-9 year olds are not going to be learning that. I may be incorrect, if I am, please let me know.
But that's not the point I'd like to make.
"It's like this. My child that I brought into this world. My child that I'm rasing and paying for. So ill decide when it would be best to teach them life lessons. Not some overpaid constantly whining teacher or government agent or politician."
Your child is going to operate in the world with other people, if you do not take the time to teach your child about body autonomy, consent, safe sex, safe sex in the context of a relationship etc, Someone could get hurt.
Not all parents do a poor job in the sex ed department, but many do a poor job, and we see the results. Rape, teen pregnancies, disease, etc.
Consent and harassment is a huge issue, especially in the late high school/university age. Many people really don't understand consent, and don't understand harassment. This stuff needs to be taught and taught early.
From my own experience, as a kid whose parents were very open and available about sex, I was actually pretty surprised at how my friend's parents dealt with the subject. It was by and large, ignored, or it turned into an embarrassing elephant in the room sort of thing, and most dangerously it lead to teen pregnancy, disease, and one run in with the police.
In my case, not so much. Condoms were purchased, sex was had or not, and I had some very helpful and open conversations with my mother when something got a little uncomfortable for me . No judgement. I was made to understand at a reasonably early age that some boys like boys, and some girls like girls, and that's ok, you like what you like, you may even like both. I was very lucky to have been in a sex positive environment, where it wasn't considered "wrong" or "dirty" or whatever.
I see these curriculum changes as a step forward.
