@jasongoroncy well, my understanding: separation of church and state was orginally intended to keep religion safe from the state and thereby permit freedom of religion - following on from the various religious persecutions in Britain and Europe.
My view - for a pluralist society to work and not descend into sectarian strife (what with all the different religions etc) it must be under the unifying umbrella of a secular state. Religion and state should be separate - that doesn’t mean religious people can’t be in government. But that they cannot seek to promulgate their religious views through that power. Otherwise - well, that’s theocracy. And that’s dangerous IMHO
