I still think of the flag as a symbol of what the US should be and what it was created to be. I don’t like to see them flown upside down. I would rather you buy a Gadsden flag, the yellow one with the snake, and fly that instead.
Ever notice that the Confederate battle flag cannot be flown upside down?
Displaying the original Stars and Bars or the Bonnie Blue flag makes a subtle point, too.
FWIW I’m pro-Union, but I also dislike seeing Al Sharpton & Eugene Robinson dancing in the end zone spiking the ball.
