Why does Aunt Alexandria not want Jem and Scout to go to church with Calpurnia and why does Aunt Alexandria want to fire Cal in To Kill a...

Aunt Alexandria is very concerned with the way her family
is perceived. It is bad enough that Atticus is defending a black man, but having the
Finch children at a black church will look even worse. Whereas Aunt Alexandria is not as
morally corrupt as say, the Ewells, one could argue that she is more racist than Link
Deas or Dolphus Raymond. Her other concern is that the children are raised properly,
especially Scout. In the absence of a mother, Scout learns by example and the only
female that she sees everyday is Cal. Cal is a wonderful caretaker for the children,
however, she is black. A black woman could not, in Aunt Alexandra's view, raise a white
girl as well as she could. She feels that now that she is there, there is no need for
Calpurnia.
