Yes. I went to the local comp growing up and there was a Roman Catholic secondary school right next to us, yet both schools were utterly separated, apart from the regular mass fights. And I totally agree with Michael - the quid pro quo for discouraging single-faith schools has to be a secularisation of state school. One girl I knew at school got round it by persuading her parents to write a letter explaining to the headmaster that their daughter was a white witch and therefore demanded to be excluded from the compulsory act of daily worship. They couldn't legally argue with it, so she got away with it
