A smallish sample of an essay (from here) that is worth reading in full:
What can be done when people are unable to see things other than in absolute terms, and so decide that their religion, being True, is entitled to do anything it can to bring about the Proper Society? All I can say is that we should all stand against such absolutism, with arms if necessary, to protect freedoms, ours and others', and the Open Society. No principle of reasoning can prevent this.
All of this relies on there being only rational actors in the consideration of how to set up society and the law. Of course, there are not. There are those who think God will come down in the End Times next week and smite all the unbelievers. Millenarian views like this come and go, and are, I suspect, correlated with social rates of change - the greater the society is changing, especially as it is modernising, the more millenarianism is about. Much religious opposition in society is, I think, opposition to modernism itself, not the specific aspects. For example, opposition to abortion is more about having some control over who may mate with whom and how in a permissive society, than it is about theological issues. ... There are always those who think it only right that they control society, because they are God's agents, or at least the agents of Providence or History.
I like the frank acknowledgment that there can come a time when revolutionary violence is needed to oppose theocracy. Thankfully we're not in that position in the West, but the situation of our friends in places like Iran may well be another story.
Wilkins is not a Gnu Atheist, but this is pretty feisty secularism.
