Obama's Kenyan birth father: In Islam, religion passes from the father to the child. Barack Hussein Obama, Sr. (1936–1982) was a Muslim who named his boy Barack Hussein Obama, Jr. Only Muslim children are named "Hussein".
Eteraz already refuted the assertion about birth fathers:
Islamic law recognizes abandonment by the biological father. Obama's Kenyan father abandoned Obama. As such, any religious imprimatur he may have had over Obama -- which is already a stretch since the man was an atheist -- is null and void. In such a situation, Obama's mother's religion is controlling. She was not Muslim. Even if someone makes the argument from patriarchy: that Obama's paternal grandparents were his rightful guardians, that would fail since they also constructively abandoned him.
There is a corollary issue here: what about the fact that Obama's second father, the Indonesian, was a "non-practicing Muslim." Doesn't his faith transfer over to Obama? The answer is no. Under Islamic law, step-fathers do not acquire ownership over the child. Their relationship to the child emanates from their relationship to the child's mother. Again, Obama's mother was not Muslim. If a practicing Muslim man marries a Christian woman with children from a previous marriage, her children wouldn't automatically become Muslim. Here, the new father wasn't even practicing.
Luttwack and the other fake experts promoting this new smear do not understand Islam. Religion is not hereditary as it is in Judaism. Islam is not a race. Just because a child has a Muslim father -- which, again, Obama didn't -- doesn't mean anything unless the child is being raised as a Muslim. At the time of birth, Muslims engage in a symbolic act -- of saying the Call to Prayer in the child's ear -- that renders a child Muslim. If Obama's father was agnostic/atheist, then he wouldn't have done such a thing.
Pipes claims to be an expert on Islam, but none of the traditional practices or concensus views above seems to penetrate his analysis. I think people of Pipes' ilk are confusing muslims with Jews. Or with Klingons (we already know muslims are Orcs).
As far as Pipes' assertion that only muslims are named Hussein, I wonder what he thinks of these shady characters:
Gen. Omar Bradley, who bore a Semitic, Muslim first name, and shared it with the second caliph of Sunni Islam, was the hero of D-day and Normandy, of the Battle of the Bulge and the Ruhr.
What about other American heroes, such as Gen. George Joulwan, former NATO supreme allied commander of Europe? "Joulwan" is an Arabic name. Or there is Gen. John Abizaid, former CENTCOM commander. Abizaid is an Arabic name. Abi means Abu or "father of," and Zaid is a common Arab first name.
It should be noted that by Pipe's logic, this fellow might also be an apostate:
Look at that beard! And he's named after a Prophet in Islam, to boot.
