I haven't seen anybody raising this issue, so I will. Barack Hussein Obama was raised as a Muslim for some portion of his life. We are told he had a Muslim father and later a Muslim step-father. Today as he runs for president he claims membership in a Christian church. Whether he would therefore be considered a former Muslim by other Muslims is the question.
The answer to this question becomes fascinating because in parts of the Islamic world leaving the faith for another religion is an offense punishable by death. There was a rather famous case of this in Afghanistan a year or two ago.
Now suppose we elect Mr. Obama President and no leader of any Islamic country can meet with him because he is an apostate. Suppose radical Muslim clerics around the world issue fatwas demanding the death of an elected U.S. President on religious grounds.
I don't claim to be an expert on Islam. I would be interested in hearing the opinions of any who do have a sense of how this would play out.
