What can I say if I agree with this statement and what new information can I provide with a scholarly source

As for whether such quantified debates are important for working historians to remain "up to date" on, I think the answer should be a resounding yes. These debates are essential for refining our understanding of historical events and their implications. The revised death toll of the Civil War, for instance, provides a more accurate picture of the war's human cost and its impact on American society. This revised understanding can lead to a different and more complete historical narrative, which is crucial for historians aiming to understand the past and its implications for the present and future.
