Homeschooling

[soliloquy]

I believe all schools give you the option to either opt-out or opt-in. I mean, students can even opt-out of dissecting frogs.

Your belief is incorrect.

All states are somehow involved in sex education for public schoolchildren.

As of January 1, 2014:
22 states and the District of Columbia require public schools teach sex education (20 of which mandate sex education and HIV education).
33 states and the District of Columbia require students receive instruction about HIV/AIDS.
19 states require that if provided, sex education must be medically, factually or technically accurate. State definitions of “medically accurate" vary, from requiring that the department of health review curriculum for accuracy, to mandating that curriculum be based on information from “published authorities upon which medical professionals rely.”
Many states define parents’ rights concerning sexual education:
37 states and the District of Columbia require school districts to allow parental involvement in sexual education programs.
Three states require parental consent before a child can receive instruction.
35 states and the District of Columbia allow parents to opt-out on behalf of their children.

State Policies on Sex Education in Schools

You can be sure that as the government becomes larger and larger, parents will have fewer and fewer rights regarding what their children are taught in school.
