Because some parents are abusive assholes?
Is there any law that would prevent your child from telling you anything? Until you can answer with a yes, you are just running in circles.
I don't need government to force my kids to tell me anything. Why are you dependent on government?
There is no law against children lying. There are laws against physicians telling the truth.
This is a matter of government protecting rights rather than asserting mandates for population control. So, this isn't me depending on government with respect to parenting. It is the opposite.
So, you are in support for 9 year old kids buying morning after pills without a prescription and without consultation with their parents. I think we are done here.
