Recently, the case of Meriam Ibrahim made international headlines. The story was that she, a pregnant Christian woman married to a Christian, was being accused of apostasy and sentenced to death for it. Some but not all of the articles about it mentioned the most troubling fact about the case: she is not even a apostate in that she was a Muslim and then defected from Islam. Instead, her absentee father was a Muslim and, by Sudanese law, this automatically makes her a Muslim, despite being raised a Christian by her Christian mother.
A case of a born and raised Christian being accused of apostasy from Islam and sentenced to death for it shows that anti-apostasy laws are a brutal tool that can be used to enforce tyranny on anyone, whether they are an apostate, a theist of another religion, or a non-apostate atheist.
