The article linked to the above title isn't, to be honest, worth reading. Rather, it's interesting because it further documents the desire of 'the people' (always vague and compelling) to see religion become more of a public phenomenon.
One thing that the author points out is that while race and class are recurring topics of discussion religion is still, taboo. Even the other dare-never-say 'politics' doesn't have anything close to the public taboo religion does. Nevertheless, day in and day out we see that religion is anything but a 'private' phenomenon. From the public execution of Christ, to Wilberforce, to the civil-rights movement, to the religious-right, we continually learn religion cannot be neatly lopped into a 'private' category. Religion always trespasses into the public, why can't we be honest about it?
'Religion,' the Duke philosopher Stanley Fish has said, 'is the new thing.' If he's correct let's let it be discussed publicly. Intelligently, compassionately, but publicly.
