I am fine with taking down the monuments of Confederate politicians like Jefferson Davis and even those CSA generals like Forest (first leader of the KKK) that clearly showed themselves to be racists.
But regardless of how or why the monuments were erected, many Confederate soldiers including their generals are entitled to be respected for their military services. That does not suggest agreement with their politics like it might for a Confederate politician.
Prior to the Civil War, states saw themselves as independent nations (not unlike the nations of the EU) who were bound in a "more perfect union" just as the current EU agreement replaced previous ones.
The purpose of this union was largely self-defense, foreign policy, and interstate trade. During our first 100 years, New England, western Pennsylvania, South Carolina, and eventually the whole South argued states had the right to secede. Again, not unlike Britain did recent with Brexit.
Up until the Civil War, that right was not resolved. Nor had the issue of slavery ever been resolved. By the time of the Civil War, states' rights and slavery reached a point where only war was going to resolve the differences of opinion.
If you live in the South, you know many refer to the Civil War as the war of Southern Independence. In that sense, like Washington, southern generals were fighting for their state's independence, a concept we can all respect. There is nothing dishonorable in defending your country. Like the Founding Fathers, these generals risked everything, but in their case they lost.
I view the Civil War "soldier" much like I view the WW2 soldier. One of my uncles died bombing Germany, one of my uncles died defending Germany in Danzig. Both honorably served their nations. But I have zero respect for Hitler and Naziism and no issue with executing those Germans that carried out the genocide of the Jews. I admire some of the German officers for their bravery and courage in serving their nation. I also admire American generals, who lead armies that killed many of my family and destroyed their homes (when that was a byproduct of their military engagements).
I don't respect the decision to firebomb Dresden or use nuclear bombs on Hiroshima or Nagasaki. Nor am I fan of Sherman's March through Georgia or America's policies to exterminate the Native Americans and any generals that participated in the attacks against women and children.
Serving your country, which is what the CSA generals did (again you need to study how Americans especially southerners viewed states vs federalism with 18th and early 19th century "eyes", not 20th and 21st century eyes, before you say they were treasonous.
Lastly, do you consider American generals during the American Revolution "treasonous" or does that change because we won?
