Most people would associate the confederacy with being in favour of slavery and so arguably some people will see the Confederate leaders those statues represent as being associated with slavery.
Yes. Most people would - because the victors write the history.
Have you read the Declarations of Independence of each of the seceding States ?
At least one would confirm all the pre-conceived ideas about slavery being the trigger. It is quite explicit in treating black slaves as mere property not people.
Other Declarations mention slavery too - alongside the right of States to make their own laws - as promised by the US Constitution - in a sort of sliding scale with one only hinting at the Federal anti-slavery law.
So for what were the thousands of ordinary Confederate soldiers fighting ?
They did not have slaves.
And how many Officers had slaves ?
So for the vast majority, surely it is a fair bet that they thought they were fighting for Independence first - with slavery being a very poor excuse ?
In the occasional German small village, there is a Memorial to WW1 soldiers. No 'glorification'. Just similar sentiments to ours.
Northern Italy has some WW2 cemeteries. Rows of headstones, similar to British War Graves. One or two have flowers placed.
In the UK, we have learned to distinguish between the Wehrmacht and the SS.
I mention these because Civil War memorials - often only remembering the dead - have been described by opponents as 'hate monuments'. Many have been defaced. Some damaged.
As often, things are not 'all good' versus 'all bad'.
