There's a lot to dislike about Obama's speech in Cairo, and I'll let everyone else slice up the speech on the many lies that Obama spoke.  But this quote in particular bothered me, though it's not a lie. 

"I consider it part of my responsibility as President of the United States to fight against negative stereotypes of Islam wherever they appear[.]"

As President of the United States, his responsibilities are clearly defined by the Oath of Office, as specified by Article II, Section I of the U.S Constitution. 

"I do solemnly swear (or affirm) that I will faithfully execute the office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States."

How the hell that retard thinks that misleading Americans about accurate stereotypes of islamic terrorists somehow preserves, or protects, or defends the Constitution of the United States is beyond me.
