Prof Roger Trigg and I had a debate about whether Britain is too secular now last Easter at the Ox Lit Festival (a CFI event). Trigg has since produced a report for the think tank THEOS that takes much the same line as he took in the debate and his earlier book. He says there has been a silent downgrading of religious rights in Britain. His conclusion is religious beliefs are special and do deserve special privileges and protections - which are currently being eroded with potentially dangerous consequences. Go here.
Several of Trigg's arguments are explicitly discussed in an early draft of the secularism chapter of my forthcoming Very Short Introduction to Humanism (OUP 2010) available here.
