Abstinence only sex education is currently the norm at public schools.
Is the program actually a Christian program? That you could really make some waves about. Anything about god is off limits.
The abstinence only part really isn't something that making a sink about will effect anything.
You can opt out, but ask exactly what your child will be doing during that time. At our public school, they divided the kids by gender for sex ed, having all the girls from two classrooms go to one room and all the boys go to the other. One gender had a study hall while the other had sex ed with the school nurse, and then it switched. (our program was an hour a week for 6 weeks)
So if I had opted my DD out of it, she would have gone to another classroom with all the boys from two classrooms and had a study hall. Which I felt was really, really inappropriate.
She went ahead and had "sex miseducation" as we decided to call it as a family. The good part was that every week she had a discussion sheet that she had to have signed by me, so I always knew the highlights of what she was being told. It was really present more balanced information, and on the plus side, we had a bunch of conversations about sex, bought some new books, etc., so it was a positive thing in her life.
The school really can't undo all your good parenting through silly stuff like this. Don't give it more power than it has, which really isn't very much.
