It's not "a piece of obvious propaganda" simply because you (one of the most vociferous "anti-birthers" in all of FR-dom) and a Zotted Obot Fogblower say it is.
This may come as a shock to you, but your own credibility and true motivations regarding pretty much anything touching on "Obama"'s true identity and his eligibility to hold the office he currently enjoys are, shall we say, suspect. Heck, you probably think the findings of Joe Arpaio's Cold Case Posse are bunk as well.
Whether Gilbert ultimately has to answer for any dishonesty or sloppy research regarding the photos aspect aside, the narrative described in Dreams From My Real Father is by far the most reasonable, plausible scenario I've encountered to describe what really may have gone down concerning the origins of the man calling himself Barack Hussein Obama. I've seen the film. Have you?
In deference to Little Jeremiah however, whose input I respect a whole lot more than I do yours, I'll give the material (only what's posted at FR, as I refuse to give LorenC any additional traffic) a thorough going-over.
