TLDW: Erika Moen (web cartoonist) wrote a book called "Let's Talk About It: The Teen's Guide to Sex, Relationships and Being Human"; in the chapter on sexting she advises teens that pictures they send to people can never be deleted and therefore they should crop out their faces and any identifying birthmarks, etc, before sending one. A concerned parent read this passage at a school board meeting to protest this books inclusion in the library. Hilarity ensues.
