The very idea of public schooling is currently under sustained challen
ge from an array of groups with sectarian social, political, religious
, and cultural agendas. Some of these challenges come in the form of p
olicy initiatives such as school vouchers, charter schools, ''parents'
rights'' movements, and the rise of home schooling and other forms of
nonpublic schooling. In the face of this momentum, the democratic sta
te must continually find ways to balance individual parental and commu
nity rights against the public interest. But the state cannot bend ove
r backward to meet every demand and, in particular, those of fanatics,
whose agendas include commandeering educational institutions or optin
g out of ''the system'' altogether. By providing a conceptual framewor
k for identifying and assessing fanaticism, and then by making the cas
e that in a democracy fanatics should not be allowed to run schools of
any kind, this article seeks to establish an outer boundary for what
forms of school initiatives ought to be permissible. Among a range of
examples included for discussion are the claims of certain fundamental
ist parents and the racialist ''Christian Identity'' religion that und
ergirds much of the militia movement.
