You're still thinking too specifically. I'm talking about the standards of society.

Homosexuality is not an illness because it has no negative affect on society.

Pedophilia does have negative affects on society. Engaging children in sexual relationships is damaging to them, and, therefore, damaging to society. I BELIEVE THE CHILDREN ARE OUR FUTURE! TEACH THEM WELL AND LET THEM LEAD THE WAY! SHOW THEM ALL THE BEAUTY THEY POSSESS INSIIIIIIIIIIIIDE!
