I really don't get this whole line of argument.
Has anyone seen him, of his own volition and not as part of an event as an elected official, engage in Muslim prayer, attend Muslim services, or let fly with Muslim cultural phrases of anger, praise, or otherwise?
All evidence is that he is a chronically lapsed Christian. So far as we know he has an affinity to black liberation theology preached by Marxist preachers with a penchant for firebrand racial and anti-US rhetoric. In so far as there is some overlap in political philosophy between this brand of Christianity and the Nation of Islam brand of the Islamic faith... it still doesn't mean he's a Muslim, sorry.
Taking severely edited clips of speeches intended for Islamic outreach and spoken before Islamic audiences doesn't cut the mustard. They are unfair distortions, not evidence... well, at least not evidence of Obama's supposed Muslim faith, only evidence of the poor ethics and morality the editors of this video.
