I don't know. I'm not a child psychologist. But, I am a conservative Republican who believes that matters like this should be left to the states to decide absent the heavy hand of the imperial federal government.
The parents in California elected the state legislators. They crafted a bill that was signed by the governor, who too was elected by parents. That's good enough for me.
I’m a believer in logic and history and I’ve seen these idiotic crusades before, and they never have any proof of anything. It’s flexing state power to gain control, imperial power wielded at the state level is no less tyranical than at the fed.
