Southern generals didn’t keep good records on casualties. The sons of the aristocracy, serving in more elevated positions, were reported preferentially.
The records available show that more family members of slave owners died for the south as a proportion of their army. Keep in mind that many southern men fought against the insurrection, and didn’t get counted in as southern casualties.
After the Wilderness campaign, Lee stopped counting casualties all together. His practice of putting snipers behind his men to stop desertions meant that his losses from “friendly fire” were very high.
You are truly insane.
