I don't usually get into faith based posts, cause on secular sites it's just pot-stirring, but I can't help myself here.
Daftpunk, speaking Catholic to Catholic here, yes, Catholic churches and schools should treat the religion as it is, not as individuals want it to be. However, it is not the State's job to make being a Catholic easy for us.
Expecting a serious and thoughtful apologetical discussion of tough theological issues on a secular parenting website is naivete at best and trolling at worst. It will win you no converts and harden the hearts of any who might sympathize in other circumstances.
Christ told us not to be of this world and Mumsnet is a microcosm of that world. The day you log on to find everyone agreeing with you is the day you're doing something wrong.
So man up, suffer for your faith a little, and don't make everyone else suffer through your flamebait.
No hard feelings, eh
