When people advocate for Confederate monuments and other symbols they are literally advocating for something that is un-American and unpatriotic.
If we had Nazi symbols on government property, would we not spend money to remove them?
Both were enemies of the country, and it's the same principle. Anyone who doesn't realize that the Confederacy was an enemy of our country surely failed US History.
I'm not a fan of the Confederacy, but to compare the Confederacy with Nazi Germany is a false equivalency. Neo-Confederates and Confederate Revivalists are a different matter.
Folks have been raised to believe Lee, Jackson, Davis, et al were heroes. And, at a certain level, they were heroic. They were brave in battle, they were courageous, and Davis was a courageous President of the Confederacy. Were they racists? Davis certainly was, and they probably all were by today's standards, and they defended the indefensible of slavery, but there were other issues that drove the Civil War besides the slave question.
This yanking out of monuments, the "kneelers" at football games; there is absolutely no good will in how they go about things. I'm not saying that this isn't a case of the shoe being on the other foot; no one cared about the thoughts and feelings of blacks for a century after Appomattox, save for Reconstruction. And the revival of Confederate imagery during the Civil Rights Revolution years are isn't about history at all. But a good part of the "dig 'em up" crowd's actions are a case of taking two (2) wrongs and making a right; it never works. The wrong is in the total disregard for the other side.
