Just as an FYI, here's the third of the four verses of our national anthem:

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 washed out their foul footsteps’ 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!

It makes me wonder why we're so ignorant of or unwilling to acknowledge 75% of the anthem—particularly this stanza—unless there's something to be ashamed of regarding our national origins. Go ahead and reverently sing the above. We were, after all, founded upon an economy dependent on slave labor and failed to change that for nearly 30 years after Britain abolished slavery; and when we did, it was with horrific bloodshed during 4 years of civil war. And so, here we are in 2016, still unable to find resolution.
