Japanese schools are outdated as institutions for information delivery. Furthermore, a significant number of schools still ban students from dating. Needless to say, they study the academic subjects forced on them, but everything they learn there is based on the premise of heterosexuality, including sex education. Teachers also convey the predetermined concept of heterosexuality to students. That hurts not only homosexual students but also others.
Schools convey a one-sided message.
Teens of late are also said to be mentally too vulnerable or too easily hurt. I think today's society easily hurts people. Typifying this is television variety shows in which members of the audience are put up on the stage and mocked. Instead of getting the public to laugh at their own performances, they laugh at audience members or people with some sort of disadvantage, including minorities. These television games are similar to bullying.
