The child is not taken away. The non-biological mother loses her status as a parent, but the biological mother is still registered as the child's mother.
This does mean, however, that if the biological mother dies the state may take the child away from the non-biological mother.
I'm sure you understand this already, but your idea is politically and morally equivalent to what's happening in the article. Everyone has the right to freedom of religion.
edit: Strange that people become like this when told that religious people deserve protections as a minority or protected class. I'd hoped to leave new athiest cringe behind at spez's place but apparently you can't have everything.
Not really, Christianity in the US was and continues to be a corporate funded endeavour. That doesn't make the belief system inherently bad, it's like most things that have been corrupted by moneyed interests.
Structured belief systems led by a man wearing entirely gold while telling everyone to follow the teachings of Christ is bad though. It's meant to control, specifically women and children.
