Protecting students from harmful sexual content is a serious issue in Texas’ K-12 schools.

A Texas parent concerned about schools exposing children to sexually explicit materials has started a petition urging lawmakers to close legal loopholes that are allowing obscene books into students’ libraries.

Obscenity is not protected free speech, and making obscene or harmful material available to minors is a crime under both federal and state laws.

But loopholes in Texas law allow giving minors access to otherwise illegal sexual content if it’s for “educational” or “governmental” purposes.
