Appropriate for Germany, not the United States
What's the difference?
The 1st Amendment
So you are saying that if the Holocaust had happened in 1940's America you would favor a statue of the American equivalents of Erwin Rommel and Adolf Hitler being in front of the local courthouse?
No, but I think it's safe to say that we would have seriously re-evaluated our entire governmental system if that had happened in the USA, just as we had the 13th-15th amendments as well as a different understanding of the relationship between the nation and the states after the Civil War.
So are you failing to understand that Robert E Lee and Erwin Rommel are morally equivalent?
Lol.
Both men were excellent generals who were much loved by their soldiers. Both men served governments with which they had misgivings and concerns but to which they felt a sense of moral obligation. But men were serving regimes that were built on the blood and genocide of a people (Confederate defenders can look up the Cornerstone speech if they think the Confederacy was based on something else).
In the end, Rommel actually tried to remove the root cause of his country's madness whereas Lee served it until the bitter end. Can anyone really justify why we should have statues that praise him? We don't have statues praising Benedict Arnold.
