By simple extrapolation we must assume that Christians (liberal christians excepted, of course) must now be forbidden to: teach, be a JP, work as a police officer, be a social worker or probation officer.
They must not have contact with the elderly or those convalescing. Indeed it is most difficult to know just where the list might end.
Logically I suppose, children should be taken into care from all Christian parents - just what Professor Dawkins has asked for, of course.
