Why might Atticus not want his kids to know about the rest of his family?

Atticus did not want his children in court because he knew they would be exposed to the lies, deceit, and racism endemic to the society in which his family resided and because of the abuse that would invariably be heaped upon his children's father by virtue of his willingness to defend Tom Robinson.

in "people in peace, not profit and war" chrisholm uses inductive reasoning for her argument against defense spending by stating that the new administration, like most americans, wanted to invest in social objectives, so they must not want to prioritize defense spending. mr. nixon said "we can delay no longer in launching new approaches to the problem that beset them", but chrisholm points out that the programs were delayed anyways.
