Disclaimer: if this guy had not been presented to us by his supporters and the lamestream media as the smartest, most well-spoken politician in a generation, I would ignore these types of comments but since he is the antithesis of both, I can't help myself.
Do you remember when Michelle Obama said, "Barack knows that we are going to have to make sacrifices; we are going to have to change our conversation; we're going to have to change our traditions, our history; we're going to have to move into a different place as a nation?" Well that is exactly what the President is doing!
But consider the idiocy of his comment:
The first Islamic center was founded in 1890.
THAT'S OVER 100 YEARS AFTER THE FOUNDING OF THE COUNTRY!
On top of that, the President failed to note that the first mosque in North Dakota was established in 1929!
Certainly does not sound very "woven into the fabric of the country" to me!
It might also be worth noting that America's first real involvement with Muslims was fighting the Barbary Pirates from Africa who looted American ships and captured American sailors, holding them for ransom or selling them as slaves. That's where the phrase, "from the Halls of Montezuma, to the Shores of Tripoli" come from in the Marines' Hymn!
