What are some examples of prejudice in Chrysalids?

One example is the Zealand woman killing everyone but the telepaths and calling everyone else hopeless savages.

Another example is the Spider Man keeping the women and kicking David out.

Harming and ostracizing Sophie's family, David's aunt and daughter, people turning each other in, etc. are also examples, but it was also the law... so it is government-mandated prejudice rather than merely personal prejudice.
