At least the School had the sense to quickly backtrack on the punishment. The teacher clearly has an agenda.
I would like to know why they were discussing homosexuality in the classroom in the first place? Who brought up the subject? Here is a puzzle, they want to discuss homosexual topics in the schools but they do not want anyone to criticize homosexuality. If they did not speak about homosexuality in schools, then no body would be talking about it in class. So they must want to discuss homosexuality in the classroom only to promote in while censoring any opposing views. Lawsuit.
