The team behind Southlake is back with the story of a neighboring north Texas school district, where a parent has accused a teacher of convincing her child to change genders. Hosts Antonia Hylton and Mike Hixenbaugh show how these types of allegations against teachers are tied to a national movement to impose conservative Christian morality in public schools. This is a special excerpt of episode 3 of Grapevine, a new six-part podcast series from NBC News Studios. To hear the show, follow now: https://link.chtbl.com/grapevine_alw_
