The problem is that, at the moment, the BNP is a legal political party. I think there is (or should be) enough control in schools to ensure that teachers with extremist views, be they political or religious, do not influence the children. If the kids come home and spout racist views, parents have a right to complain and, I'm sure, they will be taken seriously.

For example, although I am an atheist, my daughter goes to a CofE school because it's the only one in the area. They are taught about religious diversity and the various world religions and I have no worries about her being filled with Christian doctrine - rather she is encouraged to form her own opinions.
