Why does mr. Logan insist on taking Stacey with him to Vicksburg and why does mrs. Logan object?

Mr. Logan insists on taking Stacey to Vicksburg to teach him about responsibility and to expose him to the realities of the world outside their community, as he believes it’s an important step in his maturation. However, Mrs. Logan objects because she fears for Stacey's safety and is concerned about the dangers he might face in a racially charged environment. Her protective instincts reflect her desire to shield Stacey from the harsh realities of racism and violence that they encounter.
