Apart from football - or in my case rugger
yet the church of England is not a 'state religion'
I may be wrong on this but I don't think this is true.
The Church of England is technically the Established Church in England - and that makes it (by definition) a state religion.
What has happened over the course of our long history is that the practical impact of the CoE being our state religion has become effectively zero.
When I was at school back in the '60s and '70s we had to attend state mandated assemblies - which had a Christian element - every morning. I believe this is no longer the case - another example of the way we have disestablished the Church in practical terms but haven't done it in legal or constitutional terms.
I wish I didn't know now what I didn't know then
