CONWAY SPRINGS, Kan. (AP) — A Conway Springs teacher has been asked to resign after showing students an anti-bully video that depicts a dystopian society in which homosexual children bully heterosexual children. Conway Springs Middle School social studies teacher Tom Leahy is on leave and said he likely won't return to teaching because the controversial video "upset too many people." Leahy said he showed the independent film "Love Is All You Need" to three eighth-grade history classes as a lesson in tolerance last month. Showing the video was a response to an assignment Leahy gave his students to create a colony. At least one group rejected gay people in its colony. The Wichita Eagle reports the school board is expected to accept the teacher's resignation at its November 9 meeting. The newspaper's calls to several board members weren't returned Monday.
