Not to pick on Mistermix, especially because everyone makes the same mistake, but this is the Stars & Bars, better known as the national flag of the Confederacy:
To be specific, this one is the fourth national flag of the Confederacy, which was flown from 10 DEC 1861 through to the end of the Confederacy. Earlier versions, revised each time more states seceded and joined the Confederacy, had 7, 9, and 11 stars in the blue canton.
There were two other national flags of the Confederacy. The second was known as the stainless banner and had the battle flag of the Army of Northern Virginia as the canton on a white field. The third, the blood stained banner, was simply the second national flag with a vertical red stripe running opposite the canton. The red vertical stripe was added because there were concerns that if the stainless banner was flown in the field, and the canton was not visible, then it would be mistaken for a flag of surrender. Irony abounds. These two flags are below.
(That isn’t actually a bunch of white space above, it really is how the white field of the flag appears on the page)
While there were a number of other unofficial Confederate national flags, what most people call the stars and bars is not. Yes it has stars on it and yes it has bars on it, or, more accurately, a blue saltire cross. In Project Lincoln’s video, the Confederate flag that opens, closes, and is the most predominant throughout is actually the second Confederate Naval jack, which is below.
You’ll notice the lighter blue of the saltire compared to the cantons of both the stainless and blood stained banners above, which are the battle flag of the Army of Northern Virginia. Most manufacturers of these flags don’t pay too much attention to the actual color of the blue so it ranges from an even lighter blue than on the naval jack, to the blue above, to the dark blue of the battle flag of the Army of Northern Virginia, which is below.
And while the square battle standard of the traitors serving with and under Lee does make a brief appearance in the ad, the average, and in many cases the above average, neo-Confederates and white supremacists who like to fly their preferred flag or hang it on the wall or adorn their trucks with stickers of it are too stupid to realize that they’re really demonstrating their enthusiasm for the Confederate navy. Which is kind of nice because they don’t get a lot of love. Regardless, most American racists are too stupid to know they are flying the wrong flag. Just let that sink in for a minute.
The real flag of the Confederacy is the Confederate flag of truce, which was actually a white dish towel with three pencil line thin vertical red stripes along it’s right edge. It was all the Confederates had with them that they could use as a white flag when Lee surrendered to LTG Grant.
We’ll leave the last word with W. T. Sherman!
