The 'Wars of Religion' and other fairy tales

Interesting idea. It is always a bad thing to mix religion and politics, but that doesn't mean ideas from either should be censored: The 'Wars of Religion' and other fairy tales – Opinion – ABC Religion & Ethics (Australian Broadcasting Corporation):

We have bought into the idea that we cannot disagree about fundamental matters without violence. I see no reason, historical or otherwise, why this should be so. In a democratic and pluralistic society, people should be free to give any reasons for their positions that they see as significant, even if such reasons are theological.

Society would be much freer if secularists dropped the idea that their reasons alone are "worldly" and therefore fit for public consumption. It would be much more refreshing if atheists like Blackford just abandoned the pretence of neutrality and said that they find many Christian ideas batty. Then we could perhaps have an interesting conversation about the ends of human life and best political ways to attain them.
