Should Military (Active Duty, Reservist & Guard) be allowed to "sit", in support of personal beliefs, during the National Anthem?

What Offending Verse. Racist Have You Read The Stare Spangled Banner ?
You Need To Read The Story About Where , Why The Song Was Written.

I have read the history, SGT Charles Bartell, though not recently. And now I have also read about the history of which I was unaware that is associated with the brouhaha. Are you aware of it?

Apparently the mention of "slave" in verse three and "freeman" in verse four offend protestors; and that Francis Scott Key was a slave owner and did not think very highly of Africans in his day. Seems more of a protest about Key than the verses of our national anthem.

And apparently the folks protesting say that verse three reflects the political situation associated with the Battle of Fort McHenry:

"[. . .]And one of the key tactics behind the British military’s success was its active recruitment of American slaves. As a detailed 2014 article in Harper’s explains, the orders given to the Royal Navy’s Admiral Sir George Cockburn read:

Let the landings you make be more for the protection of the desertion of the Black Population than with a view to any other advantage. … The great point to be attained is the cordial Support of the Black population. With them properly armed & backed with 20,000 British Troops, Mr. Madison will be hurled from his throne.

Whole families found their way to the ships of the British, who accepted everyone and pledged no one would be given back to their “owners.” Adult men were trained to create a regiment called the Colonial Marines, who participated in many of the most important battles, including the August 1814 raid on Washington.

Then on the night of September 13, 1814, the British bombarded Fort McHenry. Key, seeing the fort’s flag the next morning, was inspired to write the lyrics for “The Star-Spangled Banner.”

So when Key penned “No refuge could save the hireling and slave / From the terror of flight or the gloom of the grave,” he was taking great satisfaction in the death of slaves who’d freed themselves. His perspective may have been affected by the fact he owned several slaves himself. [. . .]"

I can understand being offended by the history. Who isn't? It may be Key's third verse is like a statement of fact in reference to the history. Do I think our national Anthem is racist because it accurately reflects the political environment associated with the history of the battle? No. Was it a celebration of slavery when written? Not necessarily. I think it reflects the political situation. . . . which included slavery existing in the colonies, Do I think Key was racist? Yes.

I still say the national anthem is the signal to stand in honor of the flag of our nations . . . the nation we have made and continue to improve (hopefully).

Verse #3. It Is Amazing That You Have The Ability To Go Back In Time And Read Some One's Mind. Could You Tell Me If He Was Dancing And Singing Knowing That Slaves Where Killed. Why Are You Not Calling The British Racist ? After All They Where The One's Shelling The Fort.
Then There Is Verse #4. How The Hell Is This Even Remotely Racist ?
O thus be it ever when freemen shall stand Between their lov'd home and the war's desolation! Blest with vict'ry and peace may the heav'n rescued land Praise the power that hath made and preserv'd us a nation! Then conquer we must, when our cause it is just, And this be our motto - "In God is our trust," And the star-spangled banner in triumph shall wave O'er the land of the free and the home of the brave.
Please Tell Me How This Is Racist.

But Let Me Jump To Moore Resent Time. The Slave Trade The Lead To Slaves In North America Was Started By. The Dutch Slave Traders Selling Slave's To Basically The World.
Now They Did Not Go To Africa And Catch The African People In Order To Make Them Slave's. No It Was Other African Tribes Doing This.

The Uniform Code of Military Justice has several specifications which address conduct of the military, and this Code is imposed on the active duty military as a condition of their oath to obey the orders of the Commander-in-Chief and all others in positions of authority over them.
Ask Gen. Stanley McChrystal about how far those rights go for an active-duty member of the military - an incautious remark in a magazine interview caused him to be processed out of the service. He's not the first flag officer to be relieved of his post for comments which displeased the White House.

Vance Frickey - If no one ever violated the law, no one would have ever invented police. Just because it has been done, does not mean it is right.

Bergman Oswell - We have a volunteer military. No one's compelled to serve in it, but once they do agree to serve, that agreement extends to the simple matter of affirming their sworn allegiance to the nation by their posture during the playing of the Anthem and formal ceremonies involving the Flag. It's important, and goes to the issue of "good order and discipline" central to military justice and administration.

Vance Frickey - No one is compelled to vote or hold public office either, yet it remains illegal to compel people to speak in ways they disagree with in order to vote or run for office. Even private corporations are often required to respect rights, how can an organization that is part of the government be exempt?

There are many laws that have been enacted despite being unconstitutional, or that remain on the books until challenged despite having been rendered unconstitutional by the ratification of one amendment or another. Just because it has not been successfully challenged yet does not mean it must be constitutional.
