Without Googling around to ensure I have the story straight, this bill bars teachers from discussing homosexuality, but does allow them to discuss other issues concerning sexuality?
If that's true, then this is a BS bill. You either do or you don't discuss sexuality in classrooms. I don't know what age it becomes appropriate, but I think I can safely say kindergarten is a little bit young, and grade eight is a little bit too late.
More to the point, why do parents now depend on the school system to instruct their children on sexuality? Having volunteered with a few organizations catering to kids, it never ceases to amaze me how many parents want to abdicate the responsibility of parenting their children to somebody else - including a volunteer whose ethics, beliefs, morals, etc they know nothing about.
