Gingrich describes Palestinians as 'invented people'

It just keeps getting better with Gingrich. First he wants to abolish child labor laws and now this --

“Remember there was no Palestine as a state. It was part of the Ottoman Empire. And I think that we’ve had an invented Palestinian people, who are in fact Arabs, and were historically part of the Arab community. And they had a chance to go many places.”

Dear Mr. Gingrich, considering that Pakistan and Bangladesh were once a part of India and did not exist prior to 1947 and 1971 respectively, does this mean that it's okay to view the Pakistani and Bengali citizens as invented people as well? Are you really that simple minded?
