Another thought expirement: Religion and CPS
Say you are an agent in CPS [Child Protective Services]. A woman in town is saying she wants to kill her children because God told her to [They're sinners, or sacrifice whatever].
The child is then taken into your custody. A month later the mother sues for custody back. Now during the trial, she swears that she abandoned her religion. She even takes the blasphemy challenge. There is no evidence that she is still Christian or believes in God and all the evidence that she is no longer Christian and no longer believes in God.
Would you return the child?
