@icedquinn children don't really have bodily autonomy, in this case it's either parents or doctors overriding it. Children are people that shouldn't suffer from more stupid decisions of their parents, so this is in line with the rest of how they're treated.
@icedquinn this is a hard topic, as giving institutions control is dangerous but leaving it entirely with parents can be tragic. There are some things nearly everyone agrees on that parents shouldn't be able to ruin. Forgoing education at all is one of them, forgoing early treatment with good success rate for a lethal problem at least comes close. Leaving a child to die a painful death because a parent is an idiot and will attempt to treat cancer with MMC is not good.
Children aren't their parents' property and it makes sense that some of their rights as humans and citizens will be defended even against them.
@icedquinn I'd consider it similar to bodily autonomy actually. Since it's a defense from having their bodies treated badly by parents' decisions.
