CANTON — Students at a public high school outside Atlanta are rallying behind a teacher who says he’s standing up for his Christian beliefs and what he views as his right to talk about Jesus in the classroom. Hundreds of students poured into hallways at Sequoyah High School Tuesday, holding signs and chanting in support of history teacher John Osborne. Osborne said he didn’t feel supported by administrators, so he decided to take a few days off, he told WXIA-TV. He said he’s talked about God at school for years.
