no parent of sane mind wants their children to be gay. what's the point in learning about this in school?
it's not a matter of wanting something. it's accepting your children. do you think some children would turn gay if they heard about homosexuality at school? i don't think you can change your sexuality.
of course teachers should talk about it when they talk about sex in general, i don't know what age kids have sex classes in america, here we have some lessons about "sexual education" at 13. homosexuality was just mentioned.
