Then why are you not campaigning for an end to all-faith schools being anything but independent?
I must admit, I come to this as a foreigner. I'm from the US, yes, big bad ugly US. But there, if you want a faith school, you pay for it or you home educate. You can't pray in 'public'/state school, you can't even pledge allegiance to the US flag in many state schools or you can opt out (it's been a loooonnggg time since I was in one, though, I'd need to ask my sister, a high school teacher, about it).
There's no RE, there's no anything like that.
I am a Catholic, but only one child of mine is even christened, and that is in the Church of Scotland. My marriage is not even recognised by the Church, as it was a civil wedding. I had one Catholic marriage that I know was annulled, and another by a Unitarian that I don't even know would be recognised but at any rate, we divorced civally because he never wanted any children, ever, and had himself sterilised to that effect.
My children, at this school, have visits from a Church of Scotland pastor and assemblies in the kirk down the road. Historically, this is the domain of Campbell, who suppressed Catholicism in favour of the Crown, and as such, you must go into 'town' to attend Catholic Mass.
I raise no objection to this, obviously. It is a largely homogenous area.
But if there is such, why not take it to the government level instead of online deriding someone's beliefs, whatever they may be?
