US Authoritarianism

however it’s technically not

Seems weird to die on this hill because a handful of black folks might be flying it for clearly different reasons than the white folks who claim "muh heritage" but you do you. I've got underwear that has lasted longer than the confederacy did, and as pointed out by OP, the Nazis lasted longer and did more, but no one tries to pass off flying their flag as heritage.

Edit - also stealing this quote from ZombiePirate:

Our new government is founded upon exactly the opposite ideas; its foundations are laid, its cornerstone rests, upon the great truth that the negro is not equal to the white man; that slavery, subordination to the superior race, is his natural and normal condition. This, our new government, is the first, in the history of the world, based upon this great physical, philosophical, and moral truth. This truth has been slow in the process of its development, like all other truths in the various departments of science.

-Alexander Stephens, vice president of the Confederate States of America

There's only one "heritage" associated with the confederacy by anyone not in denial, and that's it.

Do you also have a list of good reasons why it should be OK for you to say the N word in different contexts?
