Because he's a Christian man, that's why. Church of Christ, to be exact. His birth-given name has no bearing on his ideology, and it's immature and petty to impune a God-fearing man that way. We have so many legitimate reasons upon which to criticize him without calling a Christian man Islamic. That's just low.
I wouldn't want to be characterized as a traitor to this nation just because somewhere in my distant ancestry, before all of this terrorist crap started up, an Islamic relative of mine whom my dad wished to honor was named "Hussein."
I fear more the wolves in sheep's clothing. Men who go by names such as Richard Reid...
And Barack (Iraq) (Saddam) Hussein Obama (Osama), just because he was raised in a Muslim household in his early years, and attended a madrass in Indonesia until he was moved to Hawaii and placed in a public school, had a "come to Jesus" moment and "became" a Christian, does that mean that the early years COULD NOT POSSIBLY have influenced a predilection to return to Islam?
I have not seen that Osama-Obama has renounced Mohammed and all his works. And if he were truly Islamic, he would lie about that anyway. It is OK for Muslims to lie to the Dhimmi.
I cut him no slack whatsoever.
Or hide their middle name. Perhaps Obama is what he appears to be, but I believe reason exists to look furhter.
