Many battles and wars (such as the one at Gettysburg), are commemorated by statues or monuments, with some areas preserved as monuments and national parks. Do you think this contradicts the message of "Grass"?
I believe that the answer to the question provided above is no. The history must never be forgotten thus a symbol must be made in commemoration of this event. Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.
