Are you suggesting that "the very fabric of our nation" goes back only to 1973 when the Sears Tower was erected?
Most people assume "the very fabric of our nation" to begin at the beginning.
Were there any Muslims at Jamestown, or on the Mayflower? Maybe there was a Muslim with Columbus on the Nina, Pinta, or Santa Maria?
Were there any Muslims in Congress on July 4, 1776? Did any Muslims ratify the United States Constitution?
These are the things that most of us consider to be "the very fabric of our nation."
That's why there is the outrage. The very things that make up "American Exceptionalism" are the things that Obama now wants to attribute to Muslims instead.

A significant percentage of U.S. slaves were Muslim. It’s likely that jazz music was created with at least a lot of Muslim influence.
