Were you born Muslim?
Unless he came out the womb declaring that their is no god but allah and Mo is his messenger and understood at least the basics of islam, no he was not born muslim.
I think it's a valid point. As an adult who has looked into religious teachings, looked into the arguments for and against, familiarised myself with centuries of teachings and traditions and interpretations, weighted things up, I can honestly say I'm an atheist. No child comes out the womb with an encyclopedic knowledge of a particular faith or philosophy and thinks "Yeah. That makes sense. I'll go with that."
I mean, seriously? A new born child has been born with the belief that a particular religion is true or not true?
Pretty much why I can't take it to seriously when someone says "This small child here is Sunni Muslim, this one here is Roman Catholic".
"Ahh, interesting. What does your two year old think of the U.N.'s response to North Korean aggression? Love to hear what they think the political fallout will be. Oh I see you have a six month old baby. Has she decided to vote liberal or conservative? They both have rather compelling arguments depending on which way you want the country to go."
