Perhaps respect for belief diversity goes in cycles

The McCarthy era saw the institutionalization of a lot of 'civic religion,' such as addition of 'under God' to the Pledge of Allegiance, and 'In God We Trust' to the currency, and the inevitably sectarian 'National Day of Prayer.'

The present pattern of secular-bashing will perhaps dissipate if/when the public (both religious and not) comes to see gratuitous God-talk in political speeches for what it is; namely delineation of in-groups and out-groups.
