Even though religious freedom is guaranteed under the constitution, it actually only goes so far and no further... I suppose if Abdul had been an atheist, or a buddhist, and had converted to Christianity then that would have been okay. But for a Muslim to convert to Christianity... Oh, no, no, no!! That is a big no-no!! And all because he is also still under the strict Islamic law.
Seems like this makes this makes a bit of a farce of the constitution.
