Read the article trying to be charitable but it along with the author's replies to comments, annoyed me a bit. He clearly doesn't understand Biblical idolatry.
Biblical idolatry presupposes the existence of the deities attached to them. The common church-ism of "you can make anything an idol/god [job, money, fear -- in the case of the article]" is completely unbiblical. It's postmodernism that's skeptical of the supernatural.
I think if Paul saw the issues we're having today with people's various addictions and distractions his response wouldn't have been to denounce those things AS idols/gods. He likely would've seen these things as being part of a spiritual issue. A symptom of the spiritual war.
So on one level the author is right for calling out those who follow the gospel of fear. Many of those operate only in the natural; meaning their apprehension of atheists/gays/muslims/etc becomes misplaced. Their apprehension is focused on people/flesh/the natural. But the battle is not against flesh and blood.
The author misses this because he's operating on the natural too. He's just operating from a postmodernistic one.
