This, and consequently other clauses that you mentioned, are rendered meaningless if a person is not even allowed to call himself what he thinks he is and his religion what he believes it is. I mentioned strange contradictions and absurdities in my last post, this is perhaps the clearest example of it.
Tell me, does freedom of religion include preaching religion, seeking converts, erecting places of worship? Tell me, also, is Ahmadia community even allowed to call themselves what they believe they are? If no, how does that mean all citizens have equal rights? Absurdities, indeed.
