Just because you didn't know something doesn't mean to say it wasn't. You do seem to be a bit obsessed with the virgin birth and resurrection though. Methinks you are not rational.
Nope. The JWs and the Mormons are sects. Neither is a cult. The Roman Catholics are a denomination of Christianity, as are the Anglicans, Baptists, Methodists, and numerous others.
Schools are indeed for educating children and that education includes educating about faith. If we don't educate children about faith we leave them vulnerable to exploitation, prejudice and ignorance, which as we know in the present climate can be very dangerous.
The first schools in the UK were established and run by the Christian church. Many of the charities we have today were started by Christians. Whether you like it or not, Christians have done a lot of good in British society and you can't change that because you can't change history.
Are you having a laugh? It looks to me as though the people kids are most at risk from being vulnerable to exploitation, prejudice and ignorance are those who belong to the church who exploit their power.
