A Republican senator wants to bar schools from teaching sex education before seventh grade.

The bill from Sen. Sylvia Allen, R-Snowflake, also deletes “homosexuality” from acts constituting “sexual conduct” in a section of the statutes, a move that appears to ban any discussion of homosexuality during sex ed courses.

Allen has already scheduled the measure for a Jan. 14 hearing in the Senate Education Committee, which she chairs, making it the first 2020 salvo in an conflict that’s been brewing since last spring, when lawmakers repealed a decades-old law that forbade the promotion of a “homosexual lifestyle.”

On the other side, Democratic Rep. Pamela Powers Hannley wants to require schools to teach comprehensive and “medically accurate” sex education on an opt-out basis. Senate Democrats plan to introduce similar legislation in their chamber.
