"Why then in Britain has secularism become seen to be hostile to religion? Because neutrality is too often assumed to require the bleaching out of all traces of faith, excluding religious belief and discourse from public life. But it doesn't, and we can see why by appeal to the notion of public reason, articulated most clearly by the late political philosopher John Rawls. Rawls was quite clear that the religious have no obligation at all to keep their faith entirely to themselves. "Reasonable comprehensive doctrines, religious or non-religious, may be introduced in public political discussion at any time," he wrote, "provided that in due course proper political reasons – and not reasons given solely by comprehensive doctrines – are presented that are sufficient to support whatever the comprehensive doctrines are said to support.""
