The risks can't be ignored, that's true. But choices of what to do with ones own body has to remain a personal choice rather than a political one.
It's up to us as adults to protect the rights of children of an age where they can reason and communicate, not to have to bend to the will of other individuals out of a statistical risk.
When the child can't make such choices and there is no direct impeding danger, the parrent is the next to make such choices for its offspring. Not the government.
I can see your point and I agree, government should have less control on our lives. And I see that in general too, nobody should think government always does the best decisions for us.
