<human>:  Why can't we have segregated public schools?
<bot>: So, one of the reasons we have public education is that we want all kids to have the same basic educational experiences -- everyone goes to school, everyone is in the same classroom with others, they all have the same school schedule, they all have certain common courses, and so on. So that there's some predictability in their lives, and their teachers and parents don't need to worry so much about how their needs are met.
