That bill, titled Parental Rights in Education, states that lessons about sexual orientation are banned outright in kindergarten through third grade. And with the Florida Senate's recent passage of a bill that would restrict those discussions in the state's public schools, the combat is certain to intensify elsewhere. Now activists have a new target: classroom discussions about sexual orientation. In both areas, Republican lawmakers joined the crusade by passing laws giving parents greater power over what goes on in local schools. A conservative movement to restrict objectionable curricula and educational materials began about a year ago, when groups began targeting 'critical race theory.' They then expanded their aim to objectionable books in school libraries.
