there's multiple sources of this, but they basically stipulate teaching young children about homosexuality in California.
I'm alright with gays, I have no beef against gay marriage or anything like that, but I strongly disagree with something so subjective and opinion-based being taught to children. School is supposed to teach you factual information only, not to advocate or damn sexuality. CA has a very tight budget, and they're already axing lots of educational programs, and instead they replace them with this.
It's like preaching a religion in school; it just doesn't belong. What the hell happened to innocence?
