Why did Abraham Lincoln say it was Harriet Beecher Stowe fault for starting civil war?

There is no evidence to suggest that Abraham Lincoln blamed Harriet Beecher Stowe for starting the Civil War. Stowe's novel "Uncle Tom's Cabin" did contribute to shaping public opinion on slavery, but the Civil War was ultimately ignited by deep-rooted tensions over slavery and states' rights in the United States. Lincoln's leadership during the war focused on preserving the Union and ending slavery.
