flip-flop
Never thought of it that way, but I suppose there's no point in faith schools being in existance if children not of that faith were to attend.
For instance, in the states, there are military schools, so the scion of pacifists wouldn't be expected to attend. Likewise, if you aren't of a particular faith, and the best schools in your area are Catholic, then your kids shouldn't be chosen over those who are actually Catholic (or Jewish, or Muslim etc).
Harsh but fair I reckon.
