There is a difference though between that and what you posted about the US. Adults are allowed to be stupid, to refuse treatments which will cure them. What your not allowed to do is impose that onto children. If that is happening in the UK I would be seriously surprised if the government is allowing it. Its the same as Blood Transfusions for children here, parents can refuse it for themselves but not for there children, the hospital and the guardianship board will automatically overrule it.
