Academics rushed to defend a former teacher at an elite New York City school who taught “pornography literacy” to high schoolers and showed first graders a cartoon about masturbation.

Justine Ang Fonte taught sex education at Dalton School in Manhattan for nine years, The New York Times reported, developing K-12 curriculums for students and speaking and offering workshops at other New York City schools.

The sex educator sparked a backlash from parents when she taught two Zoom sessions to Columbia Grammar and Preparatory School on the Upper West Side in May to junior and senior high schoolers.

The school’s head, Bill Donohue, told the Times that he understood the lecture would be under the topic “Healthy Sexuality Workshop,” but Fonte’s sex education prompted parents to take their grievances about her explicit material to the New York Post.

The publication reported that Fonte’s slides discussed “incest-themed” porn, consensual or “vanilla” porn, “barely legal” porn, “kink and BDSM” porn, “waterboard electro” torture porn, and more.
