John Freshwater discussed his creationism beliefs, disregarded evolution and failed to follow the standard curriculum while teaching eighth-grade science at Mount Vernon Middle School, board officials said.
An investigation revealed he continued teaching his beliefs even after he was ordered to stop, the Columbus (Ohio) Dispatch reported Saturday.
The investigation found Freshwater said homosexuals are sinners and branded crosses into some students' arms, the board said.
Freshwater's attorney, R. Kelly Hamilton, said his client's rights to practice religion were infringed and he plans to call for a hearing with the school board to fight the dismissal.
Hamilton said the allegations are "fabrications created by a couple of students … Not a single child has ever been harmed."
