No doubt we'll get protesters from nowhere near the school, jumping up and down and threatening violence because the religious rights of children they don't have, are being destroyed by blasphemers and kaffirs.
They knew the school was non religious when they signed up. Don't start complaining now.
Except the ban was brought in recently. You can know that it's not a faith school but not expect a prayer ban to come in. The Equality Objectives of the school state "To promote cultural understanding and awareness of different religious beliefs between different ethnic groups within our school community."
Personally I would not even consider sending a child to the Michaela School as I've seen the head on the news so I'm aware of her ethos and iirc Suella Braverman is involved somehow.
