It was a feminist doing sex ed for college students. Rather bizarre, but not as bad as the fake news of her doing it for 6th graders.
Per Snopes -
The photographs displayed in the original article were not in fact pictures of a Florida substitute teacher named Sharon Mercer, but rather pictures of
Carlyle Jansen, the founder and owner of
Good for Her (a progressive, female-friendly sex store in Toronto, Ontario), who has upon occasion been invited to give talks about sexual health at Toronto-area high schools. But Ms. Jansen told us that she also teaches sex ed classes for adult audiences, that the photographs displayed in the outrage-provoking article were snapped at a university-level (not a sixth grade) class, and that she “would not have done those positions and discussed strap-ons to that extent in a high school setting.”
Instead, someone repurposed those photos and incorporated them into a post that read as a sort of melange of moral panics, touching on fears about the threat of common core curriculum, openly gay teachers, and general ambient concerns about acceptance of homosexuality in society. As quickly as it appeared, the InfoWars post evaporated as it was scrubbed from that site.
