For further elaboration and clarification re: The AP article titled “Our National Anthem by Francis Scott Key Needs to be Revisited and Perhaps Revised ” which was published on September 11, 2016, a Snopes check on the subject determined the following.

Francis Scott Key, the wealthy American lawyer who wrote “The Star Spangled Banner” in the wake of the Battle of Fort McHenry on 14 September 1814, was a slaveholder who believed blacks to be “a distinct and inferior race of people, which all experience proves to be the greatest evil that afflicts a community.”

The offensive portion of the National Anthem which is rarely sung is the third stanza shown infra.

“And where is that band who so vauntingly swore,
That the havoc of war and the battle’s confusion
A home and a Country should leave us no more?
Their blood has wash’d out their foul footstep’s pollution.
No refuge could save the hireling and slave
From the terror of flight or the gloom of the grave,
And the star-spangled banner in triumph doth wave
O’er the land of the free and the home of the brave.”
