As for schooling question. First and foremost i’d prefer state funded schooling tosecular. It doesn’t matter what religion it is, but religion should kept as far away from the classroom as possible, unless that classroom be religious education – and that should be for comparative religious education not some reverend, priest or iman preaching.
In Scotland there does seem to be support for all schools to be non denominational (80% of the population at large and 59% amongst catholics). But it is still seen a political hot potato and the only party in the Scottish parliament who would supports the change is the Greens.
The shared campus schools are seen the compromise ‘solution’- 2 different schools sharing the one building and classrooms. But the non-denominational pupils and teachers and catholic pupils and teachers have seperate entrances, seperate toilets and seperate dining halls. Maybe ok for South Africa in the 1980s or Alabama in the 1960s but pretty poor show in these supposedly more enlightened times.
