Why would it be easier to list him as a Muslim at a Catholic school?
This seems to defy logic.
Obama/Soetero was pulled out of this school and placed in a “public” school later when his step-father deemed that he wasn't receiving enough instruction in Islam. He even took Koranic studies in Arabic, something very few Indonesian Muslim students do.
Ergo, any child Obama's step-daddy entered into a Catholic school would have to be identified as a Moslem. On the other hand, I don't think that school asked that question ~ not consistent with what I have been informed is a world-wide Catholic practice.
