In "The Chrysalids", how is the philosophy of the Waknuks similar to that of the Fringe people?I need to compare and contrast.

Well, at first glance they appear completely opposed to
each other. The society of Waknuk is implacably opposed to any form of "deviations" as a
result of the Tribulation and the subsequent nuclear fall-out, so much so that any human
that is classified as a "deviant" is neutered and then expelled into the Fringes, which
of course is the unfortunate fate of Sophie, David's childhood friend, in spite of her
parents' best efforts to prevent her "deviation" coming to
light.

So in a sense, the philosophy of the Waknuk
community has created the Fringes. However, when David, Rosalind and Petra are captured
by Fringes men towards the end of the story, they see how the Fringes people are
implacably opposed to the Waknuk community, no doubt driven by the personal enmity of
Gordon the "spider-man" for his brother, David's father, and for the way that he was
disinherited because of his deviation.

So, although there
clearly are differences along religious lines and attitudes to deviation, both groups
seem to be motivated by hatred of the other, as shown by the frequent incursions of both
sides into the territory of the other, for example, when Gordon was captured towards the
beginning of the book.
